Albert-Mangelsdorff-Weiher, Pond in Innenstadt, Frankfurt, Germany

Albert-Mangelsdorff-Weiher is a pond in Bockenheimer Anlage featuring clear water surrounded by maintained pathways and thick vegetation in Frankfurt's urban setting. Benches placed around the water's edge offer spots to sit and take in the surroundings from different angles.

The pond was renamed Albert-Mangelsdorff-Weiher in 2013 to honour the Frankfurt jazz trombonist Albert Mangelsdorff; previously it was called simply Teich in der Bockenheimer Anlage. It originated from a larger wartime fire-fighting pond, partly filled in after the war and landscaped into the Wallanlagen. Remains of the city fortifications demolished between 1804 and 1812, rediscovered in 2008 on the south bank, suggest the water is much older, possibly part of the moat of the 14th–16th century second city expansion.

The pond's name, given in 2013, honours Frankfurt jazz trombonist Albert Mangelsdorff; before that it was simply called Teich in der Bockenheimer Anlage. A few metres from the north-east bank stands the Nebbiensche Gartenhaus, built around 1810, which has housed an art association since 1950.

The pond is accessible from several entry points along Bockenheimer Anlage and fits easily into a walk through the park. The surrounding paths are flat and easy to walk, making a visit comfortable at any time of day.

Remains of Frankfurt's city fortifications, demolished between 1804 and 1812, were rediscovered during construction work on the pond's southern bank in 2008. This suggests the water may be far older than its wartime origin as a fire-fighting pond would indicate.
