The Prümerburg is a ruined hill castle on a roughly 30-metre-high lias-sandstone rock on the upper edge of the valley of the Prüm in the municipality of Prümzurlay in the county of Bitburg-Prüm in the German state of Rhineland-Palatinate.
The Prümerburg, a fief of the counts and dukes of Luxembourg, is first recorded in 1337, but was probably built in the 12th century. In the immediate vicinity there was an earlier prehistorical hillfort (Wallburgen). The castle's features include the remains of a pentagonal bergfried. The Prümerburg is believed to have burned down in 1658.
In 1337, Walter of Meysenburg is the first recorded vassal. In 1351, Godfrey of Meysenburg and his wife, Catharina of Homburg, were the enfeofees, later Prümzurlay, like Clerf, went to the lords of Brandenburg (a side line of the counts of Vianden). Subsequently there is evidence that the von Vinstingen and von Haracourt families (both by marriage) were vassals. A line of the von der Heyden family bought the Lordship of Prümerburg in the Early Modern Period, along with Niederweis and Stolzemburg.
To the northwest in the valley, the castle chapel, the Late Gothic former Chapel of St. Nicholas, has survived.
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.
