In the second half of the 14th century, the Livonian Order built the Aizkraukle Castle, a few kilometres downstream from the ancient hillfort of Livs. The ruins of the castle still remain today. Before World War I, the settlement that stood near the site of modern-day Aizkraukle was known by its German name of Ascheraden.
