Luostarinmäki is the only unified part of the Turku city that survived the conflagration of 1827. The area consists of 18 blocks of original 18th century – early 19th century buildings on their original location. Today Luostarinmäki is an outdoor museum that offers over 30 workshops from different fields of craftmanship display the City's handicrafts history and craftsmen's dwellings.
During the summer season, the museum's workshops have craftsmen working there every day. The museum's shops, postal office and cafeteria serve customers round the year.
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.
