Hernen Castle is a Dutch castle from the 14th century. Hernen Castle is located in the south of Gelderland, in the village of Hernen (municipality of Wijchen), in the far west of the Rijk van Nijmegen. It probably originated around 1350, and then consisted of only one residential tower (keep). Later it was repeatedly expanded, with the former courtyard increasingly being filled. The residential tower collapsed in the 18th century. In 1968, the television series Floris was recorded at this castle.
