On the bank of the river Daugava, Lielvarde was the site of a 13th century castle. Its ruins are still visible. Near the city centre, a 12th century fortified wooden settlement is reconstructed, called Uldevena koka pils. Uldevens is the name of a 12th century Latvian king. It is a private initiative based on archaeological samples supplied by scientific journals published in Latvia.

Defended by a robust palisade, the settlement comprises some wooden dwellings inside of which copies of everyday objects and mannequins have been placed, the latter richly attired in men's and women's clothing. During the summer, demonstrations of medieval handcrafts commonly practised in the region are performed for visitors. Together with enthusiasts experimental workshops are being created, to look into the ancient handicraft. For example, together with potters 11th — 12th century potter kilns were reconstructed, different clay dishes were made and baked, followed by the publication of an informative booklet.

The purpose of the settlement is to study history and make ancient Latvian life more popular.
