Manderscheid Lower Castle (Niederburg) was first mentioned in 1133, when it started to be built as an outer bailey of the Upper Castle. The Upper Castle was then held by Richard von Manderscheid as a fief from Henry IV, Count of Luxembourg. Around 1146 a feud started between Henry IV and Albero de Montreuil, Archbishop of Trier, and Albero besieged the Upper Castle and took it from Henry. After peace was settled the Archbishop was allowed to keep the castle. The Lords of Manderscheid then settled on the Lower Castle. The Lower Castle was then built up to become a full castle on its own.
Between 1346 and 1348 the Lower Castle was unsuccessfully besieged by Baldwin of Luxembourg, Archbishop-Elector of Trier, and William V, Duke of Jülich. Up until 1427 the damaged castle was being rebuilt by Dietrich I von Manderscheid. In 1457 the Manderscheid family were elevated to Counts by the Holy Roman Emperor, Frederick III.
In 1673 the Lower Castle was badly damaged by the French troops of Louis XIV. This started the decay of the castle, although it was still inhabited in 1794. Then the French revolutionary troops invaded the region. They found the castle empty, as the inhabitants had already fled to their lands in Bohemia. The French then destroyed the castle and, in the early 19th century, auctioned its ruin off for demolition.
The ruins of the Niederburg have been owned since 1899 by the Eifel Club and the club has slowly, but continually, restored them. They may be visited daily during the summer months. Guided group tours are also possible on request. The castle may also be booked for private events such as weddings. On the last weekend in August every year there is a medieval festival at the castle and the adjacent jousting field which receives about 15,000 visitors.
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.
