Unlike Vienna's other royal residences, Hofburg is like a city within a city. Sitting on the southwestern edge of the Innere Stadt, the 13th-century palace was the winter residence of the Habsburgs, and a center of power for some 600 years. These days, the Hofburg Palace is residence and office of the President of Austria, however extensive parts of the palace are still open to visitors.

One area of the palace is the Sisi Museum, named after Empress Elisabeth, wife of Emperor Franz Joseph, with more than 300 objects on display. The Sisi Museum offers insights both into the grandeur of the Habsburgs and into the life and death of Vienna's beloved Empress Elizabeth. You can also explore the Imperial Apartments (Kaiserappartements) where the royal family lived. Though Hofburg has about 2,600 rooms, only 18 are open for the public to tour. The oldest parts surround the Swiss Wing (Schweizertrakt), named for the Swiss guards who used to patrol the area. (Unfortunately, the silver collection is closed until further notice.)

Originally constructed from 1696 as a grand hunting lodge, Schönbrunn Palace later became the official Hapsburg summer residence. Under the supervision of Maria Theresa (the only female Habsburg ruler), Schönbrunn evolved into an expansive paradise with ornate rooms and vast elaborate gardens comparable to King Louis XIV of France's palace at Versailles. One of the finest baroque palaces in Europe, Schönbrunn was one of the first places in Austria to be declared a UNESCO World Heritage Site, back in 1996. A tour will lead you through apartments belonging to Maria Theresa as well as Emperor Franz Joseph, his wife Elisabeth (better known as Sisi) and Archduke Franz Karl. Other highlights include the Blue Staircase, the Mirror Room and the Hall of Ceremonies. Plan to spend at least an hour in the gardens, which are connected by promenades that extend from the Gloriette, a stunning Roman-style arch overlooking a vast pool. Located within the grounds is the Tiergarten, the oldest zoo in the world.

Travelers say the grounds are beautiful, the tour is insightful and the zoo is entertaining for the whole family, but many warn about how crowded this attraction gets. Some suggest visiting first thing in the morning to avoid the congested atmosphere. Others wish there had been more information about the history within the rooms themselves.

U.S. News Insider Tip: The area between the MuseumsQuartier and Naschmarkt – especially along and leading off Gumpendorfer Strasse – is a great place to explore for small, trendy bars and boutique stores. – Rudolf Abraham

Straddling the southwest section of the Ringstrasse, the MuseumsQuartier Wien is an enormous cultural institution comprising numerous top-notch museums. If you're even remotely interested in art, head to the Leopold Museum, which houses an exceptionally impressive collection of Austrian masterpieces dating from the 19th century to the present – including major works by Gustav Klimt, Oskar Kokoschka and Egon Schiele (it's the world's largest collection of works by Schiele). Next door, the Museum of Modern Art (aka MUMOK) is home to the national collection of 20th-century works by famed artists like Max Ernst, Rene Magritte and Andy Warhol. Adjacent to MUMOK, the Kunsthalle Wien showcases an ever-rotating collection of avant-garde exhibits featuring contemporary art.

Towering above the streets of the Innere Stadt, this massive cathedral is one of the true centerpieces of Vienna. St. Stephen's has stood in this very spot since the early 13th century (having replaced an even earlier church), but little remains of this Romanesque construction aside from the Riesentor (Giant's Door) and the Heidenturme (Towers of the Heathens). The Gothic structure standing today was built in the early 1300s. It was here that Mozart was married to Constanze Weber in 1782, and it was here that the great composer's funeral was held in 1791. Despite parts of it being heavily damaged by fire in the final year of World War II, it was painstakingly repaired. Today this stunning cathedral remains an active house of worship, a national icon and a top tourist attraction.

After you've toured the main section, head underground to the catacombs where you'll find the tombs of members of the Habsburg royal family, along with various cardinals, archbishops and victims of the Great Plague of Vienna. Before you leave, you should climb the 343 steps to the top of the South Tower, from where you'll be treated to a spectacular view. Or use the elevator to reach the lookout terrace at the lower, never-completed North Tower, which is also home to the largest church bell in Austria, known as Pummerin. Visitors call this one of those "must-visit" attractions in Europe, praising the gorgeous church and its surroundings.

The works at the Kunsthistorisches Museum, or Museum of Fine Arts, range from ancient Egyptian and Greek objects to masterpieces by numerous European masters, including Titian, Velasquez, Van Dyck and Rubens. In fact, the collection here is so extensive that many people say the walls of the Hofburg Palace look bare in comparison. The building itself, which opened to the public in 1891, impresses travelers as well; its facade features ornate sculptures.

Recent travelers appreciated the wide range of work on display at this museum and note just how large the building is and how much art is held within. A few suggested breaking up the day with a quick cup of coffee at the on-site coffee shop, which is in the museum's beautiful domed hall.

If you can't get your art fix at either the MuseumsQuartier or the Kunsthistorisches Museum, you're sure to find satisfaction at the Belvedere. There are actually two palaces here – separated by an ornate 17th-century French-style garden – which some say are among the best examples of Baroque architecture in the world. Formerly home to such notable Austrian figures as Prince Eugene of Savoy and Archduke Franz Ferdinand, the buildings now house an outstanding array of Austrian art from such renowned artists as Gustav Klimt (including his famous painting "The Kiss"), Egon Schiele and Oskar Kokoschka. It's in the Upper Palace that you'll find works by these and other artists from the permanent collection, while the Lower Palace houses temporary exhibitions. A third, modern building, Belvedere 21, acts as an arts and performance venue and is located just across the main road. It has just a few exhibits on at any given time. Travelers love the gardens, ornate buildings and array of paintings on display at this attraction. Many warn of large crowds.

The Belvedere sits just southeast of the Innere Stadt, between the Wieden and Landstrasse districts. It is open every day from 9 a.m. (Upper Belvedere) and 10 a.m. (Lower Belvedere) to 6 p.m. When purchased online, entrance to both sites costs 24 euros (about $26) for adults. Youths 18 and younger always explore for free. You should definitely book tickets online, as entry is limited by time slots and these do sell out. For Belvedere 21, you only need to specify the day of your visit, not the time. Guided tours are available and there are a variety of combo ticket packages available as well. For more information, visit the palace's website.

Part of the excellent MuseumsQuartier Wien, the Leopold Museum houses one of greatest collections of Austrian art anywhere in the world. Along with major works by the likes of Gustav Klimt, Oskar Kokoschka, Richard Gerstl and Max Oppenheimer, the Leopold Museum includes the world's largest and most comprehensive collection of works by Egon Schiele.

The main part of the museum is the permanent exhibition, Vienna 1900, which takes you through the most important artistic developments and changes in Vienna around the end of the 19th and beginning of the 20th centuries, the last decades of the Habsburg rule. If you only have time to visit one museum to see works from the Viennese Secession (the local style of art nouveau), the Leopold Museum gives the best overview. Visitors commented on the exceptional quality of the artworks on display, the clear and spacious layout of the museum, and the pleasant café.

On one side of the Hofburg's Neue Burg wing, and entered off Josefsplatz, is the Austrian National Library. The main reason to come here is the spectacular State Hall (Prunksaal), built for Emperor Charles VI in the 1720s, as the former Court Library. The State Hall was painstakingly restored in 2022.

Forget any ideas of what a library looks like – the Prunksaal is a baroque masterpiece. Some 80 meters (around 262 feet) long and 20 meters (about 66 feet) high, the State Hall is lavishly decorated with stucco, marble and gilding. A statue of Charles VI stands in the center of the hall, likely the work of Venetian sculptor Antonio Corradini. There are more than a dozen other statues in the hall of Austrian dukes and Habsburg rulers, by the Strudel brothers (one of whom, Paul Strudel, also worked on Vienna's Plague Column or Trinity Column, erected as a memorial after the Great Plague in 1679). The hall also contains four enormous Venetian globes. Perhaps most impressive however is the soaring oval dome, 30 meters (98 feet) high and decorated with breathtaking frescoes by the Habsburg court painter Daniel Gran, whose other work includes frescoes at the famous Klosterneuburg Abbey.

U.S. News Insider Tip: Make a point of visiting the excellent Sigmund Freud Museum, housed in Freud's former apartment and practice. It's less than a mile north of Judenplatz. – Rudolf Abraham

Judenplatz earned its name back in the 13th century when it was first designated as the Jewish Ghetto. For two centuries, this neighborhood remained the epicenter of Jewish life in Vienna, an identity that still lives among the exhibits found at the Museum Judenplatz. This small yet effective branch of the Jewish Museum Vienna (located a little south of Judenplatz) details the role Viennese Jews played in the development of city life and the persecution and expulsion of the Medieval Jewish community on the 1420s.

One of the most famous coffee houses in Vienna, Café Central was established in 1876. Right up until the eve of the Second World War, this landmark spot was a favorite meeting place of Vienna's poets and intellectuals (many of whom were Jewish). Sigmund Freud and some of Austria's most famous writers including Stefan Zweig, Peter Altenberg and Arthur Schnitzler – not to mention Russian revolutionary Leon Trotsky – frequented the cafe's tables. Given its former clientele, you can guess the cafe is an incredibly grand and atmospheric place – not somewhere you order a coffee to-go. Café Central occupies the ground floor of a magnificent building, awash with ornate decoration and Italian flourishes, which was originally home to the stock exchange and central bank.

Along with plenty of delicious cakes and pastries, Café Central serves classic Austrian dishes such as Wiener schnitzel and Tafelspitz (boiled beef in broth). Try the house sandwich (organic turkey-ham and mozzarella, served warm). They also have some vegetarian and vegan dishes on the menu. Recent travelers commented on the beautiful setting, impeccable coffee, top-notch service and excellent pastries.

U.S. News Insider Tip: Along with all the food stalls and multiple options for late night or Asian-infused dining, the Naschmarkt area is one of the city's best for LGBTQ+-friendly bars. – Rudolf Abraham

Every Monday through Saturday, hundreds of vendors flock to this vibrant market in the Mariahilf District – located just south of the Ringstrasse – to sell fresh fruit and vegetables, meat, dairy products and other local food items. This open-air extravaganza, Naschmarkt, is considered one of the largest of its kind in Austria, and it's a great intro into everyday life in Vienna. There has been a market here since at least the late 18th century. In addition to the food stalls, you'll find small eateries and cafés throughout.

Vienna has long been a musical epicenter. It was here that renowned composers, such as Mozart, Beethoven, Haydn, Mahler, Bruckner and Strauss lived, composed and performed at various points in their careers. If this history entices you, you must visit the House of Music (Haus der Musik) during your time in the city. This small but fascinating museum showcases the works of Vienna's elite musicians with displays featuring manuscripts and sound bites. Exhibits also explain the evolution of sound and the mechanics behind our ability to hear. Plus, there's an entire floor dedicated to the Vienna Philharmonic where you can even use a virtual wand to conduct the musicians. (But be careful: If you mess up they may ridicule you!) It's a great place to visit with kids, too. The facility also hosts a variety of concerts.

Travelers say if you're a classical music fan (or even a fan of the science of sound), a visit to the House of Music should be a priority. They also enjoy all the interactive elements.

St. Peter's Catholic Church (Peterskirche), which stands in the heart of the Inner Stadt close to St. Stephen's Cathedral, is one of most outstanding examples of baroque architecture in Vienna. Consecrated in 1733, it was built on the site of an earlier, Romanesque church first mentioned in the 12th century, which was destroyed by fire in the 1660s. It, in turn, probably stood on the site of an even earlier church, which sat upon the site of Roman Vindobona. Today's church makes up for its relatively compact size with its soaring dome and exceptionally lavish decoration.

The richly decorated interior features a gilded pulpit by Matthias Steinl (one of the leading baroque artists on Austria), and a magnificent baroque organ (with more than 2,000 pipes). The show-stealer however is the dazzling fresco cycle beneath the dome, the work of Johann Michael Rottmayr. Outside the church there's a relief from 1906 depicting the legendary founding of the church by Charlemagne. Travelers commented on the beauty of the decoration, and the surprising opulence of the interior compared to the relatively simple exterior. Stepping into the church always comes as a rather breathtaking surprise.

It began in 1752 as an exotic menagerie amassed by Franz Stephan, the husband of Maria Theresa (the only female Hapsburg ruler) and the country's Holy Roman Emperor. Today, Vienna's Tiergarten (also known as Schönbrunn Zoo or Vienna Zoo) is the oldest zoo in the world, home to about 750 animal species (around 8,500 animals total) ranging from tigers to lemurs – and most famously, pandas (it's one of the few zoos outside China to have these rare animals). The zoo hosts special tours and there are daily feedings that visitors can watch, with animals like orangutans, elephants, penguins and otters.

Since its founding, Tiergarten has undergone many a renovation to bring it up to par with modern facilities. Travelers say that while the cost of admission is on the pricey side, it's worth it to see the variety of animals and impressive facilities at this zoo.

U.S. News Insider Tip: Don't miss the landmark Secession Building, just a short walk from the Vienna State Opera. Head down to the basement to see Klimt's amazing "Beethoven Frieze," while listening to Beethoven's "Ode to Joy" from the Symphony No. 9 on headphones provided. – Rudolf Abraham

Since 1869, the Vienna State Opera has been the city's premier venue for the performing arts and a major focal point of Viennese life. One of the world's greatest opera houses, the Staatsoper still hosts top-notch performances (and each seat has its own small subtitles screen), and you can also tour this magnificent building on a guided tour. The 40-minute tours run every day (times vary depending on the performance schedule) and allow you a behind-the-scenes look at this beloved landmark. Tours come highly recommended by previous visitors. 

Behind the Neue Burg wing of the Hofburg, the Burggarten is a charming city park. It was originally created in the wake of Napoleon's withdrawal from Vienna in 1809 as a private garden for the imperial family. Completed around 1819, it wasn't opened to the public until 100 years later – in 1919 – following Emperor Franz Joseph I's death in 1916.

As well as being a beautiful and peaceful place to take a break from sightseeing, the Burggarten is also home to the Mozart Monument. Unveiled in 1896, this famous monument originally stood in front of the Albertina Palace, but was damaged by bombing during World War II. After restoration it was relocated to the Burggarten. The monument is a top Vienna photo-op, especially in spring when the flowerbeds are in bloom, which are shaped like a large treble clef. Other statues in the Burggarten include one of Emperor Franz Josef.

The Spanish Riding School, part of the Hofburg Palace complex, is one of the most celebrated riding academies in the world. It carries on a 450-year-old tradition of classical dressage (meticulous, careful training to achieve almost balletic movements and perfect harmony between horse and rider), featuring the beautiful white Lipizzaner horses (the younger animals are grey) which go through years of training. The stud farm is located in the village of Piber, southwest of Vienna.

Performances and Morning Exercise sessions take place in the Winter Riding School – built under Charles VI in the 1720s and 1730s – and are accompanied by classical music. During a Performance, you can see the horses and riders at the epitome of their technique, whereas the Morning Exercises are training sessions and include younger horses as well as the fully trained stallions. Guided tours are also available. Regular tours take in all the main areas, including the stables and the Winter and Summer Riding Schools, and last an hour. The 80-minute Architectural tours explore the baroque style of the Winter Riding School and takes you up into its elaborate, wooden roof structure.

Named after the Empress Maria Theresa, this large square framed by grand architecture lies between the Hofburg Palace and the MuseumsQuartier, alongside the busy Ringstrasse. The only female Habsburg ruler, Maria Theresa was empress from 1740 to 1780, a challenging period for the Habsburg monarchy which began with territorial losses and political conflict. However, Maria Theresa proved herself by leaving the empire a stronger and more stable one than the one she inherited. During her lifetime she instigated a wide range of reforms from agriculture and education to medicine and the military.

A huge monument to Empress Maria Theresa stands at the center of the square, dating from the late 19th century. The prominent neo-baroque sculptor Kaspar von Zumbusch spent more than a decade working on the project. The bronze sculpture of the Empress sits enthroned on top of a granite plinth and pedestal, above sculptures of her advisors, administrators, military commanders and figures from the sciences and arts (including Mozart as a child). The imposing monument stands more than 62 feet (the figure of Maria Theresa alone is nearly 20 feet tall). Travelers say the structure is beautiful but you won't need much time for the square itself.
