Its history is traced from the 10th century, but its current appearance in the
Gothic style originated in the 13th century. The
choir dates back to the early 13th century, whilst the
transept and
nave took shape a century later. The cathedral was damaged and restored on several occasions, making its current appearance rather modern. In the 1760s, it was given a
baroque southern facade. The current
Gothic Revival design dates to restorations in 1886–1894 under architect
Helgo Zettervall (1831–1907). The previously flat twin towers were given pointed Gothic spires. The 37 mosaic stained glass windows were created by the artist Bo Beskow (1906-1989) in cooperation with
glazier Gustav Ringström between 1945 and 1976. The motifs are mostly biblical, but the two Swedish
saints Bridget of Sweden and
Helena of Skövde are also depicted. No windows from the medieval church have been preserved. There are four bells in the two towers on the west side. The northern tower contains the large bell, cast in 1725 and enlarged in 1785, while three smaller bells hang in the southern tower. The church is long and the towers reach a height of . The church has a
medieval crypt that was found in 1949 after having been buried under stones since the 13th century. A
grave, containing a skeleton, was found in the crypt, which is within the oldest (10th century) part of the cathedral. Some remains of the original 10th century structure can still be seen in the crypt. ==Gallery==
