The Cathedral of Mondoñedo was built in Romanesque and Gothic styles, mainly between 1219-1243. In the 18th century the facade was remodeled and the towers were added. It has three naves.
The polychrome statue in the high altar, called Nuestra Señora la Inglesa (the English Madonna) was rescued from St Paul's Cathedral in London during the Protestant Reformation of Henry VIII of England.
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.
