The neogothic Alexander Church was built in 1880-1881. The church was named after the Russian tzar Alexander II. It was damaged badly by fire in 1937, but renovated next year.
Nearby the church is Pyynikki Church Park, which functioned as a cemetery from the year 1785 to the late 1880's. Although the cemetery site has been a park over over hundred years, there are still many old tombstones existing. According the legend after Finnish Civil War (1918) many people were buried to the mass grave near the church.
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.
