Hallenburg Disternich, Water castle in Vettweiß, Germany.

Hallenburg Disternich is a moated brick manor house on a slightly raised island, built in the 16th century on a high quarry-stone base. Its two storeys rise under a tall hipped roof with small dormers and two weather vanes. The courtyard front has five window axes with light sandstone surrounds and blue-and-white shutters, and a small round-arched portal sits in the recess of the former drawbridge, reached by a narrow bridge.

A Jülich ministerial family named itself after Disternich from the 13th century, first recorded in 1217 as Euerardus de Disternich. On 7 January 1288 Engelbert von Disternich opened his castle to Count Walram of Jülich for 40 marks of Cologne denarii. After 1522 Katharina von dem Bongart brought the estate to her husband Adolf von Efferen, called Hall, whose family built the surviving brick main building in the 16th century and gave the castle its name.

The name Hallenburg comes from the von Efferen family, called Hall, who built the surviving main house in the 16th century. The building later passed by inheritance and sale through families including the von Colyn, von Groote and von Geyr, and from 1719 it was held as a fief of the Cologne convent St. Maria im Kapitol. Since December 2017 it has been used as a shared house.

The property is privately owned and not freely accessible, so visits must be arranged in advance. The surroundings offer opportunities for photographing from outside and exploring the surrounding grounds.

The Hallenburg was the first castle bought by Herbert Hillebrand, the so-called "castle king", in 1964; he lived there with his family for years and had the manor house renovated in the early 1970s. After standing empty for years, the castle was sold in December 2017 and has since been used as a shared flat.
