Pernegg Abbey was founded as a Premonstratensian nunnery in 1153. It was founded by Ekbert and Ulrich, who also founded the Geras Abbey about 10 kilometres from Pernegg.
Pernegg became a community of canons in 1584. In 1700 it became an abbey but was dissolved in 1783 under the reforms of Emperor Joseph II. In the mid-19th century the premises were acquired by Geras Abbey. Since 1995 they have been used as a retreat and seminar centre for the monastery at Geras.
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.
