The Linköping Cathedral is the seat for the bishop in the Church of Sweden Diocese of Linköping. The present church is about 800 years old. However, its history starts in the 11th century, with a wooden church being built. Later, around 1120, a stone church was being constructed; a basilica of about half the size of the present building.
Around 1230 it became necessary to construct a larger church, as the basilica had become too small. The church was extended to the East, with a new choir and transept. These parts remain as part of the present church. The current altarpiece is also from that period. The next extension of the church was made following the coronation of King Valdemar, in 1251. Now, the main building was constructed, and the church received its current length. Its length is 110 meters and the height of the tower is 107 metres.
Between 1408–1420 the chapels were constructed in Gothic architecture, with large windows and star shaped vaults. The chapels were named after Saint Andreas (later renamed into Saint Mary), St. Nicolaus and St. Thomas.
Fire damaged the roof of the church in 1546 and 1567. The tower was rebuilt between 1747–1758 and again between 1877–1886 by Helgo Zettervall. However, a restoration was made in 1967, restoring the shape of the 17th century roof. The roof is covered with copper plating. The corrosion has created the green color.
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.
