The oldest parts of Västerås Cathedral date from the 13th century. It was originally built as a triple-aisled basilica in the 1230s and inaugurated in 1271. The cathedral was rebuilt and enlarged during the next two centuries. The tower was erected around 1420. The steeple was added in 1691 and it was designed by Nicodemus Tessin the Younger.
The most famous person buried to the Västerås Cathedral is King Erik XIV, the son of Gustav Vasa. The highlights of the interior are three beautiful triptychs, although there is much other fine interior furniture, including the pulpit.
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.
