Mihkli Farm Museum, found in 1959, is a previous farm typical to West-Saaremaa, with many architectural sights as well. Most buildings lie in a circle around the yard, part of which is separated by a stick fence as flower garden. Farm is surrounded by old ash trees, leafy branches used to be cut from them for sheep's winter feed.
In addition to a complete set of buildings there was a rich collection of everyday items. Almost all of the items were made by the inhabitants of this farm over two centuries.

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.
