Dragão Stadium was built for Euro 2004 and was the venue of the competition's opening ceremony. It is owned by Porto Football Club and was designed by architect Manuel Salgado. Open-air concerts are also held here in the summer. The stadium, which holds 51,000 people, has won awards, including the ECCS' European Metallic and Mixed Construction award in 2005, for its impressive design and scale. The roof is particularly unusual, made of a steel structure covered by polycarbonate sheets.
