Alsbach Castle was built around 1235 by Gottfried I von Bickenbach and called Bickenbach Castle. The Bickenbachs were a minor noble family from the Odenwald. This more-substantial structure was probably the successor to an earlier motte and bailey castle located on nearby Weiler Hill and was built to protect the family’s territorial interests after Lorsch Abbey became a subordinate of the Archbishopric of Mainz.
In 1463, the free city of Frankfurt, in retaliation for a robbery committed against one of the communal owners, overran the castle, plundered it and burnt it to the ground. It was quickly rebuilt. During the War of Succession of Landshut the Landgrave of Hessen, Wilhelm I, took the castle in 1504 without a fight, and it remained, thereafter, in Hessen hands.
During the Thirty Years War (1618 - 1648), the castle was used by the local population as a place of refuge, though afterwards it was abandoned, fell into disrepair and was used as a source of building stones for other structures. It was not until the end of the 19th century that the Grand Duke of Hesse-Darmstadt secured the ruins, and after World War II, restoration began in earnest. The castle was then renamed Alsbacher Schloss.
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.
