Found on the right bank of the Daugava where the little Karikste river flows into the Daugava, all that remains of the castle today is a set of ruined walls and foundations. The castle was built by the Livonian Order in 1224, and it was inhabited until the mid-17th century, when it was sacked during the Polish-Swedish war. The ruins offer a good view of the local gravel road that goes along the right bank of the river valley.
