Housed in an 18th-century magazine building in the Old Town area, the Narva Museum's Art Gallery covers a wide range of art, from classic foreign works to recent paintings by students of the Ida-Virumaa Art School. Don't miss the upstairs hall exhibiting rare and exquisite Russian crosses and icons, or the large hall that's home to the museum's pride and joy - a collection of paintings, sculptures and porcelain that once belonged to the wealthy Narva merchant Lavretsov. For a small fee visitors can also create a little bit of art for themselves in the museums clay workshop.

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.
