Schleppenburg, Medieval castle in Bad Iburg, Germany.

Schleppenburg was a lowland water castle and manor in the Glane district of Bad Iburg, not an elevated stone castle. Its moat was fed by the Glaner Bach, and the site lies east of Münsterstraße (B 51) via the street An der Schleppenburg. The manor house is gone and the moat filled, but the 1614 cattle house and an 1850 stable with living quarters still stand.

The Schleppenburg was a Tecklenburg fief held by the von Slepedorp family, with Johann von Slepedorp named in Iburg documents in 1358. Around 1400 it passed to the von Sladen family, then through marriage to the von Buck, von Borghorst and von Hammerstein families. In 1664 Prince-Bishop Ernst August I acquired it by exchange with Scheventorf, and it stayed with the Bishopric of Osnabrück until secularisation in 1803.

The name Schleppenburg was shared by two noble estates in the Osnabrück district, the other in Alfhausen; both were Tecklenburg fiefs held by the von Slepedorp family, which probably founded this one. In 1664 Prince-Bishop Ernst August I traded the estate from Georg Christoph von Hammerstein for Gut Gesmold, and in September 2014 about 100 re-enactors staged battles here for a "Historisches Wochenende" marking 300 years of Hanoverian rule in Britain.

The site lies in the Glane district of Bad Iburg; the street "An der Schleppenburg" branches east off the B 51 (Münsterstraße) toward the former castle grounds. The Glaner Bach, which once fed the moat, still flows between the road and the site. The manor house is gone and the moat was filled in, but the 1614 cattle house and the 1850 stable with living quarters still stand and are being restored; the moat is to be re-created.
