The water fortress of Koluvere was established in the 13th century by the bishop’s vassal Lode. The tower fortress, convention hall and cannon tower were built later. This place has been a battlefield both during St. George’s Night uprising as well as during the Livonian war. In 1439 it became one of residences of Saare-Lääne bishop. In the 17th century the fortress was turned into a manor ensemble. In 1771 the empress of Russia – Catherine II – bought it and gave it to her lover – Prince Grigori Orlov. From that time and until 1917 the castle was used by the Russian czar’s family. Later on the building has been used as a boys’ educational establishment and as a nursing home.
At present the castle is in private ownership and being renovated. It is open in advance bookings only.
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.
