Kommende Ramersdorf was established in 1230 as one of the over 300 commanderies of the Teutonic Knights following the crusades. The Georgian chapel , which had been preserved, was built between 1220 and 1230. In the 13th and 14th centuries the commanders of the Ramersdorf were mostly Rhenish nobles, ministerial and urban patricians. After a fire in 1842, the entire complex was rebuilt in Neo-Gothic style. Today Ramensdorf is a hotel.
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.
