The Château du Bernstein is a ruined castle in Dambach-la-Ville. It is among the oldest in Alsace. It was first mentioned at the beginning of the 11th century, though the northern surrounding wall can be dated to prehistoric times. The upper castle with keep, manor house and advanced works probably dates from the end of the 12th and early 13th centuries. In the Gothic era, the manor house was separated from the keep by a ditch, transformed later into a cistern. Towards the end of the 15th century, the St. Marguerite tower, so called from the name of the chapel there, was built in the rear courtyard.
Around 1835, Félix Dartein cleared the ground of the lower castle to build a house and some outbuildings which have disappeared.
Originally, the castle belonged to the Counts of Eguisheim Dabo. After the siege of 1227, it became the property of the bishop of Strasbourg and seat of the episcopal bailiffs until 1580.
The Château du Bernstein is state property and has been listed as a monument historique by the French Ministry of Culture since 1931.
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.
