This location is important in terms of Latvia’s history, because during the 12th and 13th century, this was the administrative and spiritual centre of the Lettigalian tribe, with the ruler of Jersika being Visvaldis. The castle stood on the shore of the Daugava at a height of 18 m, and this was a mighty castle hill. The flat part of the hill measured 100 x 75 m, and it was surrounded by a barrier and a defensive wall made of logs. People entered the castle via guarded gates beyond which there were residential and household buildings, as well as a small church. Archaeologists have found the remnants of log buildings, as well as many antiquities from the 10th to the 13th century that speak to extensive trade relations with other parts of Europe, including ancient Russia. In 1209, the forces of Bishop Albert fooled the people in the castle and sacked it and the ancient town that was around it. Visvaldis’ family was taken hostage, and so the Lettigalian ruler was forced to become a vassal of the bishop. The castle hill is privately owned, so please contact the owner before planning a visit.
