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:The Gravensteen is a castle in Ghent originating from the Middle Ages. The name means 'castle of the counts' in Dutch. Arnulf I (918–965), Count of Flanders, was the first to fortify this place, building a medieval bastion on this high sand dune, naturally protected by the river Leie and its marshy banks. This bastion consisted of a central wooden building and several surrounding buildings, also in wood.
In the early 11th century, the wooden building was replaced by a stone residence, consisting of three large halls that made up three storeys, connected by a stone stairwell. The monumental stone staircase, the light openings, the fireplaces built into the walls and the latrines were signs of considerable luxury and comfort in those days. There was probably also a tower.
