The founder and builder of the Reinsberg Castle is not known with certainty. However, the establishment of castle and village Reinsberg is probably due to a German nobleman named Reinhardt who had the castle built in order to protect an agricultural settlement. Already in 1197, the castle is recorded as the seat of a noble family when a member of the Reinsberg (Regensberg) family appears as a witness in a document. Their lordship did not endure for long, as they already lost major parts of their ancestral properties in the 14th century to the Schönberg family who acquired the remainder, together with the castle, in 1411. The castle remained a seat of the Schönberg family for more than 500 years. Part of the estate was a folwark in Krummenhennersdorf which was operated as a separate manor.
In the GDR, Reinsberg castle was a holiday hostel for employees of Kombinat Schwarze Pumpe, afterwards it passed into private property and was used as a hotel until 1995. It stands currently (2019) empty. The park remains accessible to visitors on foot. A local initiative has formed to save the building from ruin. The adjacent bathing park has been the open-air swimming pool for Reinsberg since 1978. The hiking trail Grabentour passes in its immediate vicinity.
The steep slope towards Bobritzsch river is a likely reason for the choice of the site for a castle-like fortification. The unprotected eastern side of the castle is defended by a moat which could only be crossed on a drawbridge. The castle was crowned by a substantial tower.
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.
