In the 13th century, the Lords of Wiltz built a fortified castle on a rocky promontory, initiating the development of the upper town of Wiltz. In 1388, the French attacked the town and burnt the castle down but it was soon repaired. In 1453, Wiltz was again attacked, this time by the troops of Philip of Burgundy. The round Witches' Tower to the east of the gardens is the oldest part of today's castle. Under Count John VI of Wiltz, the construction of today's Renaissiance style castle was begun in 1631. After delays caused by the Thirty Years War, the main building was not completed until about 1720. The old chapel was finished in 1722 and the monumental staircase leading down to the gardens was completed in 1727. The castle premises were acquired by the State of Luxembourg in 1951 for use as an old people's home.
Since 1953, Wiltz Castle has been the venue of an international music festival attracting artists and orchestras of international repute. Since 1999, the castle's stables have housed the National Museum of Brewing. The museum traces the history of beer production over the past 6,000 years, especially more recent developments in Luxembourg. The little tanning museum (Musée de la Tannerie) presents the history of the leather industry in Wiltz which dates from 1644.
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.
