Seeberg or Ostroh Castle, which was founded in the 1200s, belongs to the oldest landmarks in the region. It stands on a high rocky spur above a brook not far from Františkovy Lázně. It was probably founded as the manor house of ministeriales subject to the imperial palatinate in Cheb. Despite being almost destroyed by several fires and frequently plundered by enemy armies, Seeberg Castle has survived to our time thanks to frequent reconstructions.
The most valuable sections of the castle comprise the Romanesque Stork Tower and the Gothic south palace. Inside the castle, you may find magnificent interiors with 19th century furniture. The display also includes period clothes and an open-hearth kitchen with original kitchenware. Another part of the castle exposition is an open-air folk architecture exhibition with a display mapping the life of country folk of the district of Cheb in the 19th century. Among the exhibits, you may find the oldest logged Baroque granary dating to 1714 or a shed with a display of agricultural machinery and equipment.
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.
