Busmannkapelle Memorial, Memorial building at Sophie Street, Dresden, Germany

The DenkRaum Sophienkirche, formerly the Busmannkapelle Memorial, stands on Sophie Street at the site of the Busmannkapelle, a side chapel added around 1400 to the south side of the Sophienkirche. Its three walls are cast in fair-faced concrete, sheltered by a glass enclosure, and the chapel's open north side faces where the church once stood. The structure measures 21.60 metres long, 12 metres wide and 14.40 metres high, with a ribbed vault reproduced in steel profiles and a sandstone slab floor.

The original chapel was built around 1400 as part of a Franciscan monastery and served as a private family chapel. It was destroyed in 1945, like many structures in Dresden during the Second World War.

The memorial is named after the Busmannkapelle, a side chapel donated around 1400 by Lorenz Busmann, Dresden's mayor between 1392 and 1406, and his wife. Since February 2019 it has been one of Dresden's five Nagelkreuzgemeinden, congregations linked to the Coventry Cross of Nails.

The memorial is located in central Dresden and is easily reached on foot from nearby streets. Visitors can view the glass facade from outside and spend time in reflection without needing special arrangements.

The glass facade was deliberately designed to make the exact footprint and shape of the destroyed medieval chapel visible within the urban landscape. This is an unusual approach to keeping a lost building present through transparent architecture.
