Katarina kyrka (Church of Catherine) was originally constructed in 1656–1695. It has been rebuilt twice after being destroyed by fires, the second time during the 1990s. The Katarina-Sofia borough is named after theparish and the neighbouring parish of Sofia.
Construction of the church started during the reign of Charles X of Sweden, and the church is named after Princess Catherine, mother of the king, wife of John Casimir, Palsgrave of Pfalz-Zweibrücken and half-sister of Gustavus Adolphus. The original architect was Jean de la Vallée. The construction was severely delayed due to shortage of funds.
In 1723 the church, together with half of the buildings in the parish, was completely destroyed in a major fire. Rebuilding started almost immediately, under supervision of Göran Josua Adelcrantz, the city architect, who designed a larger, octagonal tower.
May 17, 1990, the church burned down again. Almost nothing but the external walls remained. Architect Ove Hidemark was responsible for rebuilding the church, which was reopened in 1995. The new organ was built by J. L. van den Heuvel Orgelbouw in the Netherlands.
Several famous Swedes are buried in the cemetery surrounding the church, most notable the assassinated Foreign Minister Anna Lindh, nationally popular Dutch-Swedish singer Cornelis Vreeswijk and Sten Sture the Elder.References:
Trullhalsar is a very well-preserved and restored burial field dating back to the Roman Iron Ages (0-400 AD) and Vendel period (550-800 AD). There are over 340 different kind of graves like round stones (called judgement rings), ship settings, tumuli and a viking-age picture stone (700 AD).
There are 291 graves of this type within the Trullhalsar burial ground, which occurs there in different sizes from two to eight metres in diameter and heights between 20 and 40 centimetres. Some of them still have a rounded stone in the centre as a so-called grave ball, a special feature of Scandinavian graves from the late Iron and Viking Age.
In addition, there is a ship setting, 26 stone circles and 31 menhirs within the burial ground, which measures about 200 x 150 metres. The stone circles, also called judge's rings, have diameters between four and 15 metres. They consist partly of lying boulders and partly of vertically placed stones. About half of them have a central stone in the centre of the circle.
From 1915 to 1916, many of the graves were archaeologically examined and both graves of men and women were found. The women's graves in particular suggest that the deceased were very wealthy during their lifetime. Jewellery and weapons or food were found, and in some graves even bones of lynxes and bears. Since these animals have never been found in the wild on Gotland, it is assumed that the deceased were given the skins of these animals in their graves.
