Bottmingen Castle, Medieval castle in Bottmingen, Switzerland.

Bottmingen Castle is a medieval structure in Switzerland surrounded by a water-filled moat and constructed with stone walls. The building displays early Baroque features influenced by French design from the 18th century.

The castle was built in the second half of the 13th century and initially belonged to the Kämmerer family, who served as officials to the Bishops of Basel. Major renovations took place around 1720, reshaping the structure with new design elements.

The castle is used today as a restaurant and for banquets, weddings and other festive events. Its name comes from the municipality of Bottmingen in the canton of Basel-Landschaft, and it is listed as a Swiss heritage site of national significance. Visitors can also look for the Rococo stucco in the Steinsaal, added under Martin Wenk from 1780.

The castle is located at Schlossgasse 9 in Bottmingen and now operates as a restaurant and event venue. Since it serves primarily for celebrations and dining, accessibility may vary depending on private events or functions happening on any given day.

Bottmingen is one of the few surviving moated castles in Switzerland, and unlike Hallwyl or Hagenwil it has no bergfried; its square plan with corner turrets links it to the Burgundian-Savoyard castle type. In 1780 Martin Wenk had the southeast corner lowered to courtyard level, creating today's garden terrace.
