Nyegaard-Stift

Nyegaard-Stift is a residential building in Altona-Nord with three wings arranged around a central courtyard. The structure combines stuccoed facades, sandstone ornaments, and characteristic bay windows with architectural details such as oriels and covered passages.

The building was constructed between 1899 and 1901 by Berlin architects Kuehn and Baumgarten and funded through endowment money from Hedwig Nyegaard. It was created as housing for educated women and belongs to the early social housing projects of the German Empire.

The building displays itself in red and gray sandstone with decorative towers and loggias that resemble a castle. This architectural language was unusual for Hamburg and continues to define Altona's cityscape.

The building layout follows clear paths with a central courtyard that is easy to explore from the outside. Visitors should note that this is a private residential facility not open to the public, but can be observed and photographed from the street.

The building is popularly called the Black Castle of Altona due to its dark stone color and castle-like appearance. After a major renovation in 2009, additional apartments were created while preserving the original Neo-Renaissance character.
