The head office of the Hiiumaa Museum has been based in Kärdla since 1998, located in the building known as Pikk Maja (Long House). Pikk Maja was built in the 1830s as a residence for the directors of the Hiiu-Kärdla textile factory. It was since then home to several generations of the Ungern-Sternberg and Peltzer families. During the period of Soviet occupation, different establishments and offices used the building.
The Hiiumaa Museum science and exhibition centre has a permanent exhibition, about life in Kärdla during the period of the woolen factory and also has temporary exhibitions. In addition to the exhibitions, lectures, concerts and salon evenings take place in the building’s main hall.

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.
