The Château du Nideck is a ruined castle located in the commune of Oberhaslach. Situated on the heights of the road from Oberhaslach to Wangenbourg, the castle was first mentioned in a charter in 1264, as the property of sire Bourckard, burgrave of Nideck. In 1336 there is mention of a second castle, below the first, fief of the Bishop of Strasbourg and held by the landgraves of Basse-Alsace.
Nideck then became the property of the seigneurs of the region, in the 14th and 15th centuries, according to the various regional conflicts and other events of the time. It was besieged by the Strasbourgeois in 1448. The Müllenheim family took possession of the castle and kept it until 1509. It was finally destroyed by a fire in 1636.
The castle overlooks the Nideck waterfall and is easily reached on foot. The castle has been listed since 1898 by the French Ministry of Culture as a monument historique and is owned by the state.
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.
