Varnæs Church dates from c. 1150, the baptismal font is original. The Baldachin reredos of oak is from around 1475. The renaissance style pulpit with wooden carving dates from 1606, and the crucifix circa 1250. St. Jørgens chapel on the south side was added in the 14th century, here were held services for lepers. The organ was made by Marcussen & Son, 1892. In cemetery stands a war memorial for the fallen during World War I, also a plaque in memory of those who died near Dybbøl in 1864. The freestanding wooden belfry is medieval.
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.
