Mainau Castle

To make a day of it

Burg Mainau stands in Konstanz (Landkreis Konstanz), in Baden-Württemberg, Germany. Its opening hours and prices were verified at the source on October 9, 2026.

Burg Mainau refers to the baroque castle at the centre of Mainau Island, on Lake Constance near Konstanz. Built between 1739 and 1746 by architect Johann Caspar Bagnato for the Teutonic Order, the building follows a horseshoe-shaped layout opening towards the mainland, while its main façade faces the lake. Inside, visitors find the White Hall, a former audience chamber redecorated in 1883, and the Hall of Arms, which hosts temporary exhibitions. A few steps away stands the castle church of St. Marien, whose baroque interior completes the architectural ensemble.
