Gråborg

P3

A goal of the system

Gråborg was a castle on the Swedish island of Öland, which survives today only a ruin of the largest closed prehistoric fortifications.

The non-circular castle was extended in stages and received its greatest extent in the 12th century. She had an approximately elliptical shape with 210 meters long and 160 meters wide and was surrounded by a four -meter-high wall of protection. The castle had three entrances, one of which was provided with a tower, which originated in the Middle Ages. When the castle was left to decay, is not known. During archaeological excavations inside no architectural remains were found. Due to the size of the plant is believed that it was a trading place. The small finds from the excavations are now preserved in the Provincial Museum of Kalmar.

Knudkapelle

Not far from the castle are the ruins of Saint - Knud Chapel. It is therefore assumed that there were strong links from here to Denmark and Knudsgilde. Between the chapel and the Gråborg was discovered with geomagnetic studies deeply about five meters wide moat. Traces indicate at least seven houses and a road. An interruption in the trench suggests a bridge. There may also have a well.

Detected with ground-penetrating radar

West of St. Knut Chapel and the Gråborg a deeper about five feet wide trench was about 40 meters from the castle discovered. There are traces of at least seven houses and a number of streets that all lead to Gråborg. What this is exactly is only Excavations.
