Meggenhorn Castle was built in 1868-1870 by Edouad Hofer-Grosjean from Mulhouse and in 1926 equipped with a Welte Philharmonic Organ. Today, it is mostly used as a tourist attraction and reception venue.
The castle was inspired by Châteaux Chambord in the Loire Valley France and the grounds are open to the public since 1974. The castle overlooks a vineyard and is a popular place for picnicking with access to the lake for swimming. There is also a family playground with farm animals that children can see close up. The castles view extends in over a 180° arc from the city of Lucerne, Pilatus and Rigi.
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.
