Santa Clara Monastery was founded by Don Sancho Sanchez de Velasco and his wife Doña Sancha García in 1313. Throughout the centuries almost all members of the Velasco family were buried there.
The Gothic church has a single nave and is divided into side chapels. The High Altar has three altarpieces bathed in gold in the Rococo style.
The museum shows the works of art and relics of the monastery, most donated by the family Fernandez de Velasco.
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.
