The oldest parts of Neidenstein castle date back to the 13th century. It was first mentioned in 1319 as a fiefdom of Friedrich von Venningen. 1385 the castle was still an imperial fief of the lords of Venningen whose line Venningen-Neidenstein resided at the castle. Siegfried von Venningen († 1393) and Jobst of Venningen († 1410) were Grand Masters of the Teutonic Order, Hans von Venningen († 1478) was Bishop of Basel and Siegfried III of Venningen († 1459) was bishop of Speyer. The Venningen Neidenstein family line died out in 1611.
The castle was expanded with the outer bailey in the 16th century. The murals in the castle dates from 1516. The outer gate tower dates from 1569. In the end of the 18th century the castle started to decline. In the 1890s the roof of the western part collapsed which has since it been only a ruin. In 1897-1903 much of the castle complex was restored but also the top floor of the fortified tower was removed. Starting in 1960, the restoration of the castle was continued.
Neidenstein castle is today privately owned by the family of Venningen and can be visited only occasionally.
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.
