Gurre Castle was a royal castle built in the 12th century. Four towers and a perimeter wall were added in the 1350s; it was excavated in the 19th century (from 1835) and is now restored. It is first mentioned in court chronicles in 1364, when Pope Urban V sent a gift of relics to its chapel.
The castle is associated with a legend about a Danish king named Waldemar (usually identified with the 14th-century Valdemar IV Atterdag), his love for his beautiful mistress Tove Lille (Little Tove) and the jealousy of Queen Helvig. Over the centuries, this core saga was enriched by other legends, eventually growing into a national myth of Denmark. Valdemar IV died in the castle in 1375. The myth was put into poetical form by the novelist and poet Jens Peter Jacobsen; a German translation of his poems forms the text of the huge cantata Gurrelieder by Arnold Schoenberg.
References:The ancient Argos Theater was built in 320 BC. and is located in Argos, Greece against Larissa Hill. Nearby from this site is Agora, Roman Odeon, and the Baths of Argos. The theater is one of the largest architectural developments in Greece and was renovated in ca 120 AD.
The Hellenistic theater at Argos is cut into the hillside of the Larisa, with 90 steps up a steep incline, forming a narrow rectilinear cavea. Among the largest theaters in Greece, it held about 20,000 spectators and is divided by two landings into three horizontal sections. Staircases further divide the cavea into four cunei, corresponding to the tribes of Argos A high wall was erected to prevent unauthorized access into the theatron and may have helped the acoustics, but it is said the sound quality is still very good today.
Around 120 CE, both theaters were renovated in the Roman style.
