Engeldamm 62–64, Heritage monument in Mitte, Germany.

Engeldamm 62–64 is a listed red-brick building complex in Mitte, erected 1899–1900 to designs by Konrad Reimer and Friedrich Körte as Germany's first trade union house. The main building, two side wings and two cross buildings form a courtyard layout; a four-storey annex along the Engel dam, dedicated in March 1907, repeats the unplastered brick facade with round-arched gates and windows and adds one storey.

The building opened in 1900 as Germany's first dedicated space for trade unions and worker organizations, designed by architects Konrad Reimer and Friedrich Körte. During World War I, it served as an emergency medical facility before being adapted for different purposes in later periods.

The building sits in a central location within Mitte and is easily accessible via Berlin's public transport network, making it simple to reach. Visitors can view and photograph the exterior architecture from the street, as the interior now contains residential apartments and commercial spaces.

Leo Arons, who initiated and financed the building, was buried in its courtyard after his death in 1919; after the Nazis seized the house in May 1933, the grave was levelled because Arons was a Social Democrat, a supporter of the trade union movement and Jewish. A plaque beside the gateway on the building commemorates him.
