Valleberga Church is the only known fortified round church in Scania. It was built of limestone in the middle of the 12th century. A reason for the building of the round church was that the master mason of the church, Carl Stenmester, also built churches on Bornholm, where round churches were common. The font was cut by the master of Tryde and shows one of the legends about Saint Peter and Paul of Tarsus.
In 1791, the round church was demolished and extensions were made to the north, west and south. These extensions were demolished in 1908-1910 when the round church was restored and a large cathedral-like extension was made to the west, including a new tower.
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.
