Stadion Feijenoord , more commonly known by its nickname De Kuip , is a stadium in Rotterdam, Netherlands. It was completed in 1937. The name is derived from the Feijenoord district in Rotterdam, and from the club with the same name (although the club's name was internationalised to Feyenoord in 1973).
The stadium's original capacity was 64,000. In 1949, it was expanded to 69,000, and in 1994 it was converted to a 51,117-seat all-seater. In 1999, a significant amount of restoration and interior work took place at the stadium prior to its use as a venue in the UEFA Euro 2000 tournament, although capacity was largely unaffected.
