The building of the Warburg library of cultural sciences was errected in 1925-26 by Gerhard Langmaack with the contribution of Fritz Schumacher. The oval reading hall which reaches out into the garden is especially interesting. Here the first episode of the news broadcast Tagesschau was shot. In 1993, the City of Hamburg purchased and restored the building according to the guidelines of architectural conservation. Today it harbours the department of art history of the University of Hamburg and the Warburg archive for science emigration.
