The Church of Virgin Mary is a three-aisle basilica church (the nave is higher than the aisles) with large separated chancel closed by five-side apse. It was erected in the second half of the 14th century and enlarged in 1500s. The church was partially damaged during II World War and rebuilt in 1948. In 2003 the spire and dome of the church tower were reconstructed.
More valuable monuments in the temple are pulpit coming from late Renaissance made in 1609-1630 by master from Słupsk, Paweł Waltersdorf and funded by the guilt of amber-processors (with 43 members at that time). The pulpit is covered with bass-relieves, richly ornamented polychromed and gilded. The entrance to the pulpit is embraced by a portal (the lock in the door comes from 1609). Marvelous, first final of the pulpit, the so called amber crown from the first half of the 17th century was taken away during II World War. Worth attention are also hanging candelabra – some Baroque from the 18th century, some Neo-Rococo from the 19th century – as well as numerous Baroque candlesticks form the 17th-18th centuries and later from the 19th century.
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.
