Kruikenburg Castle, Medieval castle in Ternat, Belgium

Kruikenburg is a stone castle in Ternat featuring multiple towers with architectural elements from both medieval fortifications and eighteenth-century residential modifications. The building stands within park grounds and part of it now houses De Brug primary school, run by the Christian Brothers.

In the twelfth century, the Lords of Wezemael built a watchtower at this strategic location near the County of Flanders border. The structure was later transformed and expanded into a residential castle.

The name Kruikenburg refers to the stone jugs that once stood on several castle towers, each carved from rough stone and topped with a weather vane. A gilded jug with a weather vane now stands on the tower above the entrance gate as a reference to those old jugs. Local stories say Ternat residents brought jugs to the castle when taking refuge, since they could not predict how long they would stay; other tales link 'kruik' to 'kriek', suggesting a cherry orchard once surrounded the castle, though no evidence confirms these stories.

The park around the castle belongs to the municipality of Ternat and is freely accessible to the public. The castle itself houses part of the De Brug primary school, so the building can only be viewed from outside during school hours. The former moat has been filled in and now serves as a parking area and playground.

A former underground passage that once connected the castle to Saint Gertrude's Church now functions as a wine cellar beneath the property. This hidden space reveals how the two buildings were once linked together.
