Château de Streversdorp (Château de Graaf) is a medieval fortress in Montzen, dating to the 13th century and named after its original 13th-century owner Egidius de Triversdorp. The castle's thick 1.5-meter walls are protected by extensive moats fed by two ponds, with a three-arched stone bridge and entrance gate topped by a 17th-century oval decorative element. The central keep contains a notable vaulted chamber. Protected as a classified heritage site since 1954, the castle remains privately held and is not open to the public, preserving its historic character for centuries.
