The tower Ter Heide is a 30-meter high keep. Its unique floor plan is in the shape of a Greek crucifix. The tower was built in 1350 for Gerard van der Heyden who was bailiff for Brabant and who became noble by marriage. The tower had underlined his status. The tower counts six floors that are connected by a spiral staircase and is surrounded by a moat. The building beside the keep was erected in 1631 and carries the coat of arms of the d'Eynetten-Borghrave family. The keep cannot be visited but you can admire it from close by from the public road.
