On the highest spot, there are the remnants of two palaeo-Christian basilicas of the 5th century that where places that welcomed the worshippers until the pre-Christian years. In the sanctum many sailors had been frequent visitors because they had been travelling to the island in order to transfer marble. The sailors used to engrave on the stepping-stones the names of their beloved ones and theirs, too.
References: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.
