Hallwyl Castle, Water castle in Seengen, Switzerland
The castle stands on two islands within the River Aabach, featuring fortified walls, residential buildings, and defensive structures surrounded by water.
Built in 1265, the castle underwent reconstruction after Bernese troops burned it down in 1415 during the conquest of Aargau.
The Museum Aargau maintains exhibits inside the castle that display artifacts and information about the noble Hallwyl family's regional influence.
Visitors can access guided tours throughout the year, with the museum providing detailed information about medieval Swiss architecture and lifestyle.
Archaeological excavations between 1910 and 1916 were led by Swedish archaeologist Nils Lithberg under Wilhelmina von Hallwyl's supervision.
