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:Visby Cathedral (also known as St. Mary’s Church) is the only survived medieval church in Visby. It was originally built for German merchants and inaugurated in 1225. Around the year 1350 the church was enlarged and converted into a basilica. The two-storey magazine was also added then above the nave as a warehouse for merchants.
Following the Reformation, the church was transformed into a parish church for the town of Visby. All other churches were abandoned. Shortly after the Reformation, in 1572, Gotland was made into its own Diocese, and the church designated its cathedral.
There is not much left of the original interior. The font is made of local red marble in the 13th century. The pulpit was made in Lübeck in 1684. There are 400 graves under the church floor.
