Haus Busch was built in early medieval times, although the exact date is unknown. Today it is still unfinished, as planned reconstruction in the 18th century was not completed. The entire house is rectangular and encloses a large courtyard. The first owner, as far as can be ascertained, was the land-owner Beissel von Gymnich. In the 15th century ownership was transferred via marriage to Michael von dem Bongart. At the end of the 17th century the building was acquired by the von Groote family, who also planned the grandiose reconstruction which was never completed. In the mid-19th century Haus Busch was sold to a wealthy individual, whose descendants are the present owners.
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.
