Borre mound cemetery (Borrehaugene) is an exceptional large area of burial mounds in Scandinavia. Today, seven large mounds and one cairn can be seen. At least two mounds and one cairn have been destroyed in modern times. There are also 25 smaller cairns and the cemetery may have been larger. Some of the monuments are over 45m in diameter and up to 6m high. Borrehaugene provides important historical knowledge and can be seen as evidence that there was a local power center from the Merovingian period to the Viking age.
The first investigations of the cemetery took place in 1852. Local road-builders used one of the mounds as a gravel-pit and in the process destroyed large parts of a richly equipped grave in a Viking ship. Antiquarian Nicolay Nicolaysen examined what was left of the mound. The grave contained weapons and riding equipment suggesting it was a man's grave. The excavations uncovered an unusually good selection of craft work, much of which is on display at the Viking Ship Museum in Oslo.
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.
