This elaborate church sits on the popular piazza by the same name. The church was built in honor of St. Mark the Evangelist, whose remains were stolen in Alexandria, Egypt, by a couple crafty Venetians, intent on bringing him to rest in Venice. (What made them crafty? They smuggled the remains to Italy in barrels of pork fat.) 

Crafted from many different styles of architecture, today the basilica's opulence shines from nearly every corner – from the four full-size bronze horses that guard the entrance to thousands of square feet of mosaics to the Pala d'Oro — an elaborate altar piece commissioned in Byzantium by the Venetians. If you look closely at the center gable on the exterior of the basilica, you can even see a statue of St. Mark along with Venice's emblem: a lion with wings. 

U.S. News Insider Tip: You don't need to make a reservation for a gondola ride. Instead, speak with a gondolier in person the day you want to ride. You may be able to negotiate a lower price or longer ride if you're traveling during off-peak months, or if you find a gondolier along one of the side streets. – Holly D. Johnson

Considered to be the main street of Venice, the roughly 2-mile Grand Canal is one of the city's most popular and highly photographed attractions. Recent travelers recommend hiring a gondolier for a romantic row along the canal. If you're hoping to do this option, plan to fork over between 80 and 120 euros (about $87 to $132) for the ride.

Taking a gondola ride is a must-do when you're visiting a city that rises directly from a network of canals. A relaxing journey on one of these light, flat-bottomed boats will help you admire the historic charm of Venice from a range of new angles, and to explore neighborhoods and buildings you won't see on foot.

You can prebook a Venice gondola ride online if you prefer, which typically costs at least $80 for two adults. Some of the best gondola tours you can book online come from companies like Walks of Italy, Venice Tours and The Roman Guy.

Several centuries ago, if you wanted to cross the Grand Canal, the Rialto Bridge was the only way. There are now four major bridges that cross the canal, but Rialto is by far the most famous.

The bridge's current incarnation is the handiwork of Antonio da Ponte, who beat out Michelangelo and Palladio for the job. Antonio da Ponte's name translates to "Anthony of the Bridge," and he built the Rialto Bridge entirely of Istrian stone after it collapsed multiple times from previous designs. Predicted to fail by critics, the bridge still stands and is considered an engineering marvel. 

The Teatro La Fenice is one of Italy's most popular opera houses, and one that has almost faced its demise from not one, but three big fires since opening in 1792. Locals and visitors alike joke at the name (which translates to Theater of the Phoenix), and how it has coincided with the theater's unfortunate history: like a phoenix rising from the ashes, La Fenice has lived on.

Although renovated in 1996, the historic opera house still has an old-world feel with decadent, intricately designed gold interiors outfitted with plush, red velvet chairs, making it the perfect setting to take in the auditory/visual pleasure of classic Italian opera. In addition to opera and musical performances, there are also a variety of dance – particularly ballet – performances scheduled throughout the year. For those with a tight itinerary, the theater offers day tours.

Torcello is a northerly island in the Venetian lagoon that sits nearby Burano, another island and tourist hot spot. Torcello features a range of archaeological finds, including the so-called "Attila's Throne" and the Palazzo del Consiglio — the Gothic-style seat government of the island. The Museum of Torcello is also worth a visit according to past visitors, mainly due to its displays of early Christian artifacts and the other finds from the island.

Most tours to Torcello also include stops at the nearby islands of Burano and Murano, which are both known for their artisan crafts and glass blowing. These tours typically cost $25 to $40 per person and last six to seven hours. Each one includes boat transportation with several interesting stops that vary by tour operator.

This particular bell tower was constructed in the early 20th century as a replica of the 16th-century original. The original structure provided the optimal setting for Galileo Galilei's presentation of the telescope; it also served as a stage for tight rope walkers who would humor the doge (the highest Venetian official at the time) with their feats during the Flight of the Angel celebration. Today's campanile is used for sightseers desiring a Venetian panorama – though one with few canal views, oddly, since most of the canals are obscured from its 324-foot height.

Most visitors say the attraction is well worth your time and makes for a great photo. To avoid crowds, travelers say it's best to go early in the morning or later in the evening. If you join one of the best Venice tours, you'll likely pass by the iconic landmark on your jaunt through the city.

St. Mark's Square, or Piazza San Marco, is considered by many to be the heart of Venice. As the largest square in Venice, St. Mark's Square is the only piazza in the city. Lining the square are multiple historical sites including St. Mark's Basilica, St. Mark's Campanile and Doge's Palace, as well as a number of restaurants, making it the perfect spot for leisurely people-watching and wine sipping. The square even has a handful of dueling piano bars that let you sit down and relax in a decadent setting, although the cost of food and drink at any of them is exorbitant.

Along with intricate architecture and hearty plates of spaghetti carbonara, visitors will be met with throngs of tourists, pigeons and vendors selling souvenirs. If you hoped to pick up a gondola hat or a carnival mask during your trip, this is the place you will find them.

Centuries ago, the Bridge of Sighs, which connects the Doge's Palace to dungeons, was used to transport prisoners from the courtroom to the prisons. Legend has it that the Bridge of Sighs, or Ponte dei Sospiri, was named for the sighs prisoners like Giacomo Casanova would utter as they took one last look at the outside world through the bridge's windows as they made their way to prison for good. On a much lighter note, Venetian lore says if two lovers kiss on a gondola under the bridge, they'll be granted eternal bliss. 

Recent travelers offer mixed reviews on the Bridge of Sighs. Those who enjoyed it appreciated the details of the architecture and unique placement of the bridge, saying it was a nice photo-op, especially while the gondolas passed underneath it. Those who weren't as smitten noted its lack of accessibility as the main drawback, saying that merely looking at the bridge was underwhelming. Other disgruntled visitors pointed out that the number of tourists, combined with the small amount of viewing space, made the bridge barely visible. For a better viewing experience, consider tagging along on one of the best Venice tours.

The Santa Maria della Salute was built to celebrate the end of the plague in 1631 and is dedicated to Our Lady of Health. Nowadays, many will recognize this magnificent Roman Catholic Church as the backdrop for many photos of Venice. There's a good chance you'll see it whether you take the time to go inside or not – at least from a distance. In fact, you can easily see the Santa Maria della Salute over the Grand Canal from Piazza San Marco. The church itself stands out due to its white marble facade and the 125 statues that adorn it, but there's much to see and explore inside.

The basilica features famous paintings by Titian and Tintoretto, as well as a remarkable sculpture called The Queen of Heaven Expelling the Plague. A 13th-century version of the painting "Madonna and Child" is also found within the basilica.

Views from the Venetian Lagoon give the Doge's Palace an ethereal look – almost like it's floating on top of water. But it's fitting, as the Doge's Palace (or Palazzo Ducale) has witnessed an intriguing history in its role as the residence of the doge (leader), the seat of government and the palace of justice. Everything from execution orders to the affairs of Venetian leaders was carried out here; and a web of secret passageways and hidden doors reveals a decidedly mysterious past.

Along with the attraction's historical significance, Doge's Palace is located in the busy St. Mark's Square, which means it sees a lot of foot traffic. It isn't uncommon to see a line wrapping around the building, so book your tickets in advance, and if you can't do that, arrive right when it opens to avoid crowds.

Originally an academy, this building was later turned into the Galleria dell'Accademia museum by none other than Napoléon. Today, it's filled with an expansive collection of Venetian art from the 14th to the 18th century by artists such as Bellini, Tintoretto and Veronese. 

If you enjoy art – especially Renaissance art – then you'll probably enjoy this museum. If not, you might be disappointed. Travelers who enjoyed this museum were primarily self-proclaimed art enthusiasts, while those who didn't identify as such reported being a bit bored.

The Basilica di Santa Maria Gloriosa dei Frari, sometimes referred to simply as Frari, is a gothic-style church that was finished in the 14th century. The exterior is minimal in comparison to Saint Mark's Basilica because the Franciscans who built it wanted the building to emulate their beliefs on living a life of poverty. The interior, however, is a different story. Inside, you'll see works by Titian, Bellini and Vivarini, among other famous artists, and all for a cheaper price than the city's art museums.

Recent visitors appreciated the minimal entrance fee and the fact that it sits away from the frenzy of the Piazza San Marco. Others admired its intricate interiors, as well as its bevy of artworks, calling the church a "must-see."

In 1516, Jews in Venice were forced to move to a small northwestern section of the island. Considered to be the world's first ghetto, residents were only allowed to leave the neighborhood during the day and were then locked up at night and guarded. Today, this area is a part of the Cannaregio sestiere (district) and is filled with restaurants and shops (some offering kosher products) and several synagogues, which are open for touring. Although it's free to wander around the neighborhood – and you might want to do just that – the synagogue tours do cost.

For a deeper understanding of the ghetto's history, recent travelers recommend booking a walking tour; some of the best Venice tours include stops here. Several water bus lines stop near the neighborhood, but you can also reach it on foot. 

Expat American art collector Peggy Guggenheim dedicated her life to gathering this impressive body of 20th-century contemporary art. The collection, which is housed in the Palazzo Venier dei Leoni on the Grand Canal (also Peggy's former home), contains works by artists such as Magritte, Picasso, Pollock, Chagall and Dalí. In the sculpture garden, you can pay your respects to Peggy herself (she was laid to rest on the property), as well as her beloved dogs, who are buried beside her.

Many travelers agree the Peggy Guggenheim Collection is well worth the visit. Some visitors were keen to point out that getting to know Peggy's life, on top of seeing the exceptional art, made the experience more unique than merely visiting a museum. Others who also enjoyed the museum said its modern collection is a nice break from the traditional Renaissance paintings often seen in Venetian museums. 

The Correr Civic Museum, also known as the Museo Correr, is a large museum that displays art and artifacts from Venice's history as well as the former royals' quarters. If you're also planning to visit Doge's Palace (the former government seat and leader's residence), the standard ticket includes entry to this attraction.

Those who visited the museum said they were pleasantly surprised at how much they enjoyed the stop, considering it wasn't on their must-see list (though they recommend you add it to yours). Others enjoyed the museum's peace and quiet and said it's a great escape from the crowds in Piazza San Marco. Reviewers were also pleased with the on-site cafe.

Ponte dell'Accademia is one of the four bridges that crosses the Grand Canal in Venice. While not as famous as the Rialto Bridge, its wooden structure makes it truly unique from other Grand Canal bridges in Venice that are made of metal or stone. It crosses the southern end of the canal where it connects the Dorsoduro and San Marco neighborhoods. Consider stopping by the Gallerie dell’Accademia or the Peggy Guggenheim Collection before or after viewing the bridge, as both are nearby.

Visitors say this bridge not nearly as crowded as the Rialto, and that the views of the canal and surrounding neighborhoods are spectacular. They also note that a vaporetto stop is nearby, so it's easy to visit the bridge by boat if you don't want to walk. Not only will you want to cross the bridge to get views of the water, but also you’ll want to take photos of the bridge from the surrounding buildings and walkways, according to past visitors.

U.S. News Insider Tip: Many books at Libreria Acqua Alta are for decor only. Not everything you see is for sale. – Holly D. Johnson

The Libreria Acqua Alta is often called the "most beautiful bookstore in the world," and it's easy to see why. From its ancient stone walls to its cobblestone floors and embellished (and sometimes flamboyant) decor, there's a lot to see here other than books.

Ca' d'Oro is a patrician palace that was originally built in the 15th century in the Renaissance style coupled with Gothic and Islamic elements. Built by Giovanni and Bartolomeo Bon (famous father and son architects and sculptors of the time) at the request of the procurator of St. Mark, the building is located along the Grand Canal. Several stories high, the palace facade is adorned with marble terraces and intricate architectural design. The building features ornate cornices and cresting that was made to please local Venetian patrons at the time.

The building is worth a look due to its elaborate exterior, but art lovers should note the Ca' D’Oro Franchetti Gallery is housed inside. Past visitors said that a trip inside was just as meaningful as an outside view, mostly due to the exceptional collection of art and heirlooms. Art you can view in this palace-turned-gallery includes sculptures, antique furniture, 16th-century Flemish tapestries, paintings and more.

Located near the famous Rialto Bridge, the Rialto Market is a centuries-old market that features everything you would expect including fruit, fish and vegetables. Of course, many travelers head here to pick up souvenirs as well, some of which wind up being edible. Visitors to the market have said it's a vibrant and busy place that's ideal for buying local herbs and sauces, or trying out meats, cheeses, spices and freshly caught seafood.

What should you do while visiting the market? You can walk throughout and try interesting foods and sauces, and there are places to sit down and eat or relax. Hours can vary, but the produce market is typically open 7:30 a.m. to 1 p.m. Monday through Saturday and the fish market is open the same hours Tuesday through Saturday. To avoid crowds, try visiting first thing in the morning.
