Böttstein Castle, Medieval castle in Böttstein, Switzerland.

Böttstein Castle stands at the edge of the village of Böttstein on the left bank of the Aare in the canton of Aargau. The von Roll brothers built the present complex with its manor house and chapel between 1615 and 1617 on the site of the older castle. It now operates as a hotel and restaurant.

The Barons of Böttstein, first recorded in 1087, built the castle in the 12th century; their line died out in the early 13th century. After passing through the Tiefenstein, Wessenberg and Hallwil families, it was bought on 5 June 1606 for 1,800 florins by the von Roll brothers, who from 1615 demolished parts of the old castle and built the present castle and chapel.

The chapel showcases intricate stucco work created by craftsmen from Northern Italy, reflecting how artistic techniques and styles flowed between Switzerland and the Italian regions.

The property is accessible as a hotel and restaurant, making it a convenient base for exploring the Aargau region. Visitors should note the elevated setting, which should be taken into account when planning arrival.

The castle was acquired in 1965 by Nordostschweizerische Kraftwerke AG, the association of cantonal power companies that later became Axpo Holding. Its technical staff moved into the building while the Beznau Nuclear Power Plant was under construction between 1965 and 1972. The 1971-1974 renovation then turned it into a country restaurant and hotel, and it later passed into private ownership.
