Villa Rustica in Leutstetten was a roman estate built around the year 133 AD and was in use probably only 50 years. The house was probably abandoned by its inhabitants when they had to flee from the invading tribe of the Marcomanni. Most of what was left was taken away and possibly reused during the Middle ages. Today the Villa Rustica site is restored.
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.
