The re-opening of the renovated Rijksmuseum, scheduled for mid-2008, has been set back to the end of 2009. The delay is due to extra security requirements against theft and burglary following recent art thefts from other museums and the drawing up of an environmental impact report. Financed mainly by the Dutch government, the substantial rebuilding and modernisation of the museum began in 2003. The Philips wing, where the Rijksmuseums most important works are exhibited, is still open to the public.
