Located on an elevated area, the Brustem Castle (Burcht van Brustem) is recognizable by its ruined tower (donjon) and surrounding earthworks. From the central mound, visitors can observe the gently rolling terrain around Brustem, with traces of old moats and defensive embankments visible in the grassy landscape. The combination of openness and quiet at the site encourages contemplation of the strategic value that led to this location’s selection in medieval times. While other motte castles exist in the region, the Brustem Castle is notable for its unique polygonal keep and the presence of both inner dry and outer wet moats encircling it.

Archaeological and Historical Findings

The earliest written records relating to the castle date to the late 12th century. Construction likely took place between approximately 1170 and 1175, after which it became an important local fortress. The layout includes a central raised motte encircled by an inner dry moat, an earthen defensive wall, and an outer moat filled with water, together forming strong protective barriers. The donjon’s polygonal shape is uncommon and was built with stone sourced nearby. Following the year 1366, the castle gradually lost its military importance and fell into disuse, eventually becoming ruins. Archaeological studies have uncovered remains of reinforced outer walls, towers, and parts of the curtain walls, with evidence showing several phases of building and repair spanning nearly 200 years. Nowadays, only half of the tower wall remains standing, which has recently been restored. 

Accessibility and Visitor Information 

From St. Lawrence Church, a paved path leads to a steep staircase that takes you to the top of the hill and the ruins of the castle. This is a walk of about 100 meters. Due to the stairs, this route is not suitable for wheelchair users. A visit to Brustem Castle is free of charge and the grounds are open to the public.
