Koknese Castle (Latvian: Kokneses pils, German: Burg Kokenhusen) is a complex in Koknese, in the Vidzeme region of Latvia, dating from the 13th century. The castle was situated on a high bluff overlooking the Daugava river valley. In 1965 a hydroelectric dam was built downriver, creating a water reservoir that partially submerged the castle and flooded the surrounding valley.
The castle was heavily contested between Polish, Swedish and Russian forces in the 16th and 17th centuries. It changed hands many times, while the native inhabitants endured periodic slaughter, capture, and famine. In 1701, during the Great Northern War, Koknese was blown up by retreating forces to avoid the strategic castle falling into advancing Russian hands.
