Saint Nicolas and Saint Wenceslas Church in Cieszyn is a Romanesque rotunda to serve the role of a castle chapel and a stronghold church.
The rotunda was erected within the walls of the castellan stronghold at the top of Castle Mount (built in the 10th century and the first half of the 11th century). The first reference to the rotunda comes from 1223, where it was described as St. Nicolas Chapel, obliged to pay a tithe to Norbertine’s sisters in Rybnik. The end of the 13th century and the entire 14th century was related to a reconstruction of the castle and replacement of wood by bricks. The Romanesque rotunda was adapted to the Gothic castle: the level of the floor was raised by two meters, Romanesque windows in the apse were walled up and bigger, Gothic ones were created.
At the time of the conversion of the lower castle in 1838-40, the Romanesque walls of the temple were ringed by a brick wall. New and bigger windows were walled out and a new, tin helmet was put up. The level of the interior nave and the exterior area was raised (the building was almost halfway up rimmed by soil). The Romanesque chapel received a classical division of the façade adjusted to the style of the castle. The design of a romantic pavilion was created by Joseph Koernhausel. The interior of the Rotunda was decorated by a neo-gothic wooden altar and a picture of Saint Wenceslas.
The Rotunda of Cieszyn as one of the oldest monuments of Polish architecture is depicted on the current Polish 20 PLN banknote.
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.
