The Sunken City is located in the bay of Agios Vlasios, on the beach “Kalymnios” of Ancient Epidaurus. Although not a huge site, the underwater city of Epidaurus is very unique and fun to explore. The ruins lie very close to the shore and just 2 meters below the sea level.
The architectural remains include traces of an ancient port, various walls and a cluster of three buildings, the closest of which is located only 45 meters from the shore. This is the structure you’ll be seeing when visiting the site. Archeologists believe these are the remains of a rural Roman villa from the 2nd century, which was inhabited by a wealthy Roman family and their staff.
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.
