The museum of Kihnu was established in 1974 into the old schoolhouse. Expositions are divided between four rooms. Two of them are dedicated to the everyday life of the island through centuries: tools, clothes, handicrafts, furniture. The other two are dedicated to the local representatives of naïve art and to other famous men from Kihnu: Theodor Saar, a researcher in the studies of local lore; Enn Uuetoa, a captain and Peeter Rooslaid, a silversmith. All in all the funds of the museum include 700 items. The museum has also a collection of paintings by naivist painters of Kihnu origin and many works by the most famous painter Jaan Oad.
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.
