Roma Abbey was built in 1164 by Cistercian monks. The monks established a religious and agricultural centre for the entire Baltic Sea region. After the Reformation in the early 16th century, the monastery was abandoned. It was then under the Danish Crown. The monastery building was partly demolished and the church was used as a stable. In 1645, through the peace treaty in Brömsebro, Gotland became Swedish again.
In 1733, County Governor Johan Dietrich Grönhagen, build a new stately residence, using material from the old monastery in the construction. No major changes have been made since then. It was used as the residence for the County Governor until 1822. Today impressive ruins are well known for the Shakesperian plays that are performed here every summer.
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.
