Aldealseñor medieval palace once belonged to the López de Salcedo family, due to the fact that on the façade you can see their coat of arms. It was built between the 14th and 16th centuries and it has a great tower that stands 26 metres tall. Due to the orientation of the tower, instead of being used as a defensive structure, it seems to have been just a decorative feature of the palace. The spectacular façade has two entryways, beautiful ashlar windows and doors, and the coat of arms and medallions.
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.
