Wasserschloss Hehlen, Renaissance château in Hehlen, Germany.

Wasserschloss Hehlen is a three-storey château built from limestone rubble masonry, its four wings enclosing a square courtyard. Two round towers with Welsh-style cupola roofs stand at the southeast and northwest outer corners, while two polygonal stair towers rise inside the courtyard at the same corners. A moat surrounds the building, crossed by a bridge on the southwest side, and the high hipped roofs are covered with Solling slabs.

Fritz von der Schulenburg and his wife Ilse von Saldern commissioned construction of the château between 1579 and 1584 in the Weser Renaissance style. The building was erected during a period when such fortified residences displayed the wealth and power of local nobility.

The courtyard displays double portraits of the founding couple and their alliance coat of arms above two round-arched portals visible during a visit. These artworks show the family that shaped the place and their local connections.

The grounds are open to visitors, and the restaurant-café in the restored outbuilding provides a comfortable place to spend time on the estate. The location near the Weser River makes walking along the water a natural part of visiting the site.

The free staircase on the northwest side, built at the end of the 19th century, crosses the moat to the meadows on the Weser bank. It was added during the 1886–1888 alterations, which also inserted a stair hall and remodelled the Rittersaal. The earlier stone bridge on the west side has not survived.
