It was rebuilt by Charles V, Holy Roman Emperor during the 16th century after the local rulers of the city supported him during the Revolt of the Comuneros. On the facade of the arch appear people of importance to the city of Burgos and Castile, such as Diego Rodríguez Porcelos, the founder of the city, Jueces de Castilla Laín Calvo and Nuño Rasura, El Cid, Fernán González and Charles V himself.
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.
