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.
References:The stone church of Gamla Uppsala, built over the pagan temple, dates from the early 12th century. Due to fire and renovations, the present church is only a remnant of the original cathedral.
Before the arrival of Christianity in Sweden, Gamla Uppsala was the seat of Swedish kings and a ceremonial site known all over northern Europe. The settlement was home to royal palaces, a royal burial ground, and a great pagan temple. The Uppsala temple, which was described in detail by Adam of Bremen in the 1070s, housed wooden statues of the Norse gods Odin, Thor and Freyr. A golden chain hung across its gables and the inside was richly decorated with gold. The temple had priests, who sacrificed to the gods according to the needs of the people.
The first Christian cathedral was probably built in the 11th century, but finished in the 12th century. The stone building may have been preceded by a wooden church and probably by the large pagan temple.
