The ancient theatre of Lindos lies at the foot of the west slope of the rock of the Lindos acropolis. It had 19 rows of seats, most of them carved into the rock although somewere built, as were the endmost cunei and the side retaining walls, which do not survive. Today only the rock-carved sections are preserved: the circular orchestra, the three central cunei of the lower cavea and parts of the two neighbouring ones, and the central section of the upper cavea. The orchestra of the theatre is circular, also carved into the rock.
The theatre is dated to the 4th century BCE and had a capacity of 1,800-2,000 spectators. It is connected to the great city festivals in honour of Dionysos, the Sminthia, which included theatrical, musical and athletic competitions, processions and sacrifices. In the 3rd century BCE, directly adjacent to the theatre was built the Tetrastoon, a rectangular building with an internal colonnade, perhaps a sanctuary of Dionysos Smintheus.
References:The Clementinum is a historic complex of buildings in Prague. Until recently the complex hosted the National, University and Technical libraries, the City Library also being located nearby on Mariánské Náměstí. The Technical library and the Municipal library have moved to the Prague National Technical Library at Technická 6 since 2009. It is currently in use as the National Library of the Czech Republic.
Its history dates from the existence of a chapel dedicated to Saint Clement in the 11th century. A Dominican monastery was founded in the medieval period, which was transformed in 1556 to a Jesuit college. In 1622 the Jesuits transferred the library of Charles University to the Klementinum, and the college was merged with the University in 1654. The Jesuits remained until 1773, when the Klementinum was established as an observatory, library, and university by the Empress Maria Theresa of Austria.
