Odenhausen Castle was first built in the 11th century on the hill. In the Middle Ages, the fortification was expanded into a moated water castle. The castle was first mentioned in 1316. In 1560 Ludwig von Blankart converted it into a Renaissance residence.
A bridge leads across the outer moat through a Baroque gate into the farmhouse and an another bridge leads over the moat to the two-winged mansion. The portal is decorated by a coat of arms.
Since 2005, the castle is owned by the Vieten couple.
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.
