The Oberburg or 'Upper Castle' in Manderscheid is located on a hilltop that was levelled in order to construct the castle. It had, as can still be seen from the ruins, an almost triangular enceinte and a five-story bergfried or fighting tower that has been made accessible again. From the bergfried there is a clear view of the Niederburg or 'Lower Castle', the town of Manderscheid and the countryside of the Lieser valley.
The earliest record of the castle, which is first historically known from the feud over St. Maximin's Abbey in front of Trier between Count Henry the Blind of Namur-Luxembourg and Archbishop Albero of Trier, between 1141 and 1146. The free lords of Manderscheid first appear in 1142 in the list of witnesses in a deed of gift.
In the 14th century, the village of Obermanderscheid gave its name to the Electoral Trier Amt of Manderscheid, which existed until the late 18th century. However, the seat of government was not at the castle, but in the Kellerei of the neighbouring village to which Elector Baldwin had granted town rights in 1332 (according to other sources they were granted by King Louis the Bavarian as one of a number of rights). The local estates of the Elector of Trier formed a sort of bridgehead into the surrounding sovereign territory of Luxembourg. In 1673 the castle, still owned by the Electorate, was finally destroyed by French troops.
Today the ruins of the Oberburg were thoroughly renovated in 1921 by the municipality of Manderscheid, on whose land it stands, and it is open to the public.
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.
