Honeburg, Former moated castle in Haste, Osnabrück, Germany

Honeburg is a former moated castle on the northeastern edge of Haste in Osnabrück. The estate consists of a two-storey manor house with a half-hipped roof on older foundations, two farm buildings, a gatehouse and the St. Aloisii chapel added in 1866. The manor's central axis is marked by external staircases and gables; until the 19th century it stood in a pond.

Honeburg was first documented in 1344 as a castle owned by the Eifeler family. Major renovations in 1651 transformed its architecture, and it later came under the ownership of the Ostman von der Leye family, who have held it since 1793.

The estate has passed by marriage through four families: the von Kerssenbrock in 1469, the von Boeselager in 1597 and the Ostman von der Leye in 1793, who still own it. The chapel of St. Aloisii, added in 1866, stands with the manor house, two farm buildings and the gatehouse.

The estate is private and cannot be visited; the gatehouse, manor house, two farm buildings and St. Aloisii chapel stand together at the northeastern edge of Haste. The complex is best seen from the surrounding public paths and roads, where the buildings can be viewed without entering the grounds.

The protective moat was filled in during the 1880s when nearby coal mining exhausted the local water sources. This shows how industrial activity directly altered the physical form of a historic structure.
