Burg Engelsdorf, Medieval water castle in Aldenhoven, Germany.

Burg Engelsdorf is a former water castle in Engelsdorf, part of Aldenhoven, on the Merzbach stream. Its thick walls and the moat once fed by the Merzbach still show how heavily fortified it was. The Gothic vault in the tower was secured in 2007 at a cost of 50,000 euros.

The castle was first documented in 1080 as the ancestral residence of the Lords of Engelsdorf. It passed to the Palant family in 1476, marking a significant change in its ownership and role.

Since 1989 the castle has belonged to the Chilean artist couple Fernández-Ortíz, who run an atelier, a foundry and a wood workshop inside it. The former moated castle is thus a place of artistic craft work rather than a museum.

The castle is best explored on foot as its layout is compact and easy to navigate. Visitors can view the exterior and surrounding grounds freely, though it is wise to check ahead if interior areas with artist studios are open to the public.

The castle walls and moat still show how heavily fortified it once was; the moat was fed by the Merzbach. The enclosing defensive wall around the courtyard and water castle survived until 1850. Since 1989 the Chilean artist couple Fernández-Ortíz has owned the castle and runs a studio, foundry and wood workshop in it.
