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.

Aizkraukle Castle (Latvian: Aizkraukles pils; German: Ascheraden) is a ruined medieval castle, located on the right bank of the river Daugava in Latvia to the west of the modern town of Aizkraukle. The castle was built in the second half of the 14th century by the Livonian Order. From 1334 to 1480 it was the seat of a Komtur.
History
In 1559, Aizkraukle was seized by the Poles. In 1577 it was captured by the Russians. The castle was still standing in 1633, but was in ruins by 1680. Today remains of the foundations are still visible, and there is a fragment of a wall up to 5 metres high. The picturesque ruins serve as a popular local tourist destination.
The structure should not be confused with Old Aizkraukle Castle (Latvian: Vecaizkraukles pilskalns; German: Alt-Ascheraden), another medieval castle site, of the 13th century, a few kilometres downstream.
