In December 2003, the main building of the museum closed for a major renovation. During this renovation, about 400 objects from the collection were on display in the 'fragment building', including Rembrandt's The Night Watch and other 17th-century masterpieces.
The restoration and renovation of the Rijksmuseum are based on a design by Spanish architects Antonio Cruz and Antonio Ortiz. Many of the old interior decorations were restored and the floors in the courtyards were removed. The renovation would have initially taken five years, but was delayed and eventually took almost ten years to complete. The renovation cost € 375 million
