Marstall Lübeck, Medieval stable building in Lübeck, Germany.

Marstall is the surviving complex of buildings around the Marstallhof, the courtyard between the Burgkloster and the Burgtor, first mentioned in 1298. The remaining structures adjoin the Burgtor to the west, and the gatehouse above the entrance to the courtyard still stands. The complex is part of Lübeck's city fortifications and a protected component of the old town's World Heritage site; it now serves as a youth centre.

The Marstall was first mentioned in 1298 and served as the guard post of Lübeck's order keepers, the Reitendiener, from the Middle Ages into the modern era. Two councillors, the Stallherren or Marstallherren, supervised it, and a captain led it. Besides stables it held a smithy and, until the Lauerhof prison was built in 1909, the city prison. The smithy with its Renaissance facade on Große Burgstraße was demolished in 1894 for the neo-Gothic courthouse; the gate building over the entrance to the Marstallhof survives.

The Marstall was overseen by two councillors, the Stallherren or Marstallherren, and run by a captain. From the Middle Ages into the early modern period the Marstallhof housed Lübeck's mounted order-keepers, the Reitendiener. The surviving gate building over the entrance to the courtyard recalls this guard post beside the Burgtor.

The surviving Marstall buildings adjoin the Burgtor on its west side, around the Marstallhof between Burgkloster and Burgtor, in Lübeck's old town. The gate building over the entrance to the Marstallhof is preserved; the Marstall smithy on Große Burgstraße was demolished in 1894. The buildings now serve as a youth centre, so the courtyard is in use rather than open as a monument.

The Marstall forge, with its Renaissance facade on Große Burgstraße, was demolished in 1894 for the neo-Gothic courthouse, but the gate building over the entrance to the Marstallhof survives. The remaining Marstall buildings adjoin the Burgtor to the west.
