At the end of 2003, the Adriaan Willem Weissman building was closed at the insistence of the fire department; renovation work began. The Stedelijk took up temporary residence in the Post CS Building, where it would remain for 4.5 years.[2] In 2005, the museum established a partnership with The Broere Charitable Foundation; on behalf of the Monique Zajfen Collection, the museum acquired contemporary European artworks, which were placed at the museum on long-term loan. In 2006, debates and lectures were organized in the context of the exhibition 'Mapping the City', which explored the relationship of artists to the city.
