This fortified gatehouse served as the official entry to the city ever since its construction in the 14th century, as part of the Grand Rampart which surrounded Verdun in the Middle Ages. The gatehouse was offered to the city by Wautrec, a rich citizen who was an alderman. It symbolised the new status of Verdun which was made an “imperial free city” in 1374. By this the city was obliged to maintain its own ramparts and to look to its own defence in the case of an attack.
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.
