Burg Loburg, Medieval fortress in Möckern, Germany

Burg Loburg is a medieval fortress in Möckern with a central keep, auxiliary buildings, and stone walls forming a defensive complex on elevated ground. The ruins still display the structure of a typical stronghold from that period.

The first documented mention came in 965 through a deed of donation from Otto I, though the site originated as a Slavic fortification. It was later converted into a German stronghold and expanded.

The name Loburg derives from the Slavic settlement called Priborn, recorded in 1292 as a castle; a non-Christian Slav named Pribor(n) served as bailiff there in 1114. The site is a station on the Romanesque Road (Straße der Romanik), a route linking medieval monuments in Saxony-Anhalt. The keep and barrel-vaulted cellar are what remain of the medieval core.

The medieval core keep and barrel-vaulted cellar survive, while the surrounding 18th- and 19th-century buildings stand on the former outer bailey. The site lies in Loburg, part of Möckern in the Jerichower Land district. Visitors should check locally whether the grounds are open before travelling, as access is not guaranteed.

The keep is the only surviving part of the medieval core; the rest of the site was quarried away for building stone after the Thirty Years' War. The later administrative buildings were put up on the outer bailey, and the old bridge was replaced by a stone one in 1756.
