Alzey Castle, constructed in the 13th century, was the residence and headquarters of the district administration. The castle of Alzey was a favoured place of residence for the Palsgraves during the time of both Ruprechten, Ruprecht ll and Ruprecht lll. who was King Ruprecht I of Germany from 1400 - 1410.
In the 15th and 16th centuries the castle was built into a representative castle complex which was badly destroyed during the Palatine War of Succession. As a result of the romantically inspired castle restoration movement of the 19th century, the ruin was rebuilt and restored to its historical splendour at the beginning of the 20th century. Since this time it has been used as the district court house.
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.
