Kasteel Onsenoort

Kasteel Onsenoort is a medieval castle with a sturdy residential tower now integrated into a larger monastic complex that includes prayer halls and communal spaces. The structure sits within planted grounds where the original fortress architecture blends with later religious additions.

The castle began as a fortified residence at the close of the 14th century but faced early destruction and reconstruction during regional conflicts. In the early 1900s French Cistercian monks purchased the property and transformed it into a working monastery.

The monastery uses the medieval tower and surrounding buildings for spiritual retreats and community gatherings. Visitors can sense how the religious purpose shapes the rhythm of daily life in this place.

The grounds are best explored on foot with good walking shoes, especially if you plan to wander the gardens. Check visiting hours before arriving since the monastery remains an active religious community with private spaces.

During World War II residents hid valuable items within the thick castle walls as a way to protect them from occupation forces. These concealed objects remain a quiet reminder of how people adapted to wartime circumstances in this location.
