Untersuchungsgefängnis Holstenglacis, Remand prison and cultural heritage monument in Neustadt, Hamburg, Germany.
The Untersuchungsgefängnis Holstenglacis is a remand prison in the Neustadt district of Hamburg where people are held while awaiting trial. The building is listed as a protected monument and continues to function as an active detention facility.
The building was constructed in the 19th century and has served as a detention facility within Hamburg's justice system ever since. During World War II, European resistance fighters were executed here, a fact marked by a memorial plaque installed in 2018.
The name Holstenglacis refers to the open ground that once stood in front of the city's old fortifications, and the building still carries that name today. A memorial plaque on the outer wall marks the fate of resistance fighters who were executed here during World War II.
The facility sits in the Neustadt district and is easy to reach on foot or by public transport from the city center. As it remains an active prison, the interior is not open to the general public, but the exterior and the memorial plaque can be seen from the street.
This building is one of the few places in Germany where an active prison and an officially recognized memorial site share the same walls. The daily routine of the justice system and the memory of wartime executions exist side by side here, with no separation between the two.
