Kasteel Nieuwermolen is a 15th-century fortified water fortress constructed in traditional brick and sandstone, featuring distinctive stepped gable rooflines and an L-shaped layout around a central keep. Located on the border between Sint-Ulriks-Kapelle and Asse in the Dilbeek region, the castle is accessed via a 300-meter tree-lined avenue and surrounded by grounds with an octagonal ice house from 1836 and rare mature trees including a North American amber tree. A protected heritage monument since 1962, the castle remains privately inhabited though it may be viewed from distance along local walking routes.
