Cortewalle Castle, Medieval castle in Beveren, Belgium

Cortewalle Castle is a moated castle in Beveren, built of white sandstone in Flemish Renaissance style. Its light grey stone facade faces the water, with shuttered rectangular windows, a stepped gable at the left end and another at the right corner above a small projecting round oriel. A tall octagonal turret with a steep pointed roof stands at the far right, and the steep dark roof carries small dormers and two weathervanes.

Cortewalle Castle dates from the 15th century and is one of the oldest castles in the Waasland. It was long held by the Triest family, who enlarged it; Joos Vijd left it to his nephew Joos Triest. In 1671 it was sold to Joannes Francis Goubau, and it later passed to the de Brouchoven de Bergeyck family, who sold it to the municipality of Beveren in 1965.

The name comes from Ten Wallen, rendered Cour-ten Walle in French. The castle housed the De Bergeyck family archive, scattered after 1960 and reassembled here from 1997; Beveren signed a loan agreement with the family in 2000. In 1964 the first season of Kapitein Zeppos was filmed here as Belderbos.

The castle itself can only be visited by appointment, while the surrounding park is open to the public. The municipality of Beveren has owned the castle since 1965 and keeps the De Bergeyck family archive there. A metal ladder hangs against the lower wall on the water side.

The name of the place has shifted significantly over time, reflecting changes in the local language and influences in the region. What was originally called Ten Wallen became Cour-ten Walle and eventually Cortewalle, showing how words evolved through Dutch and French usage.
