Barça's new stadium replaced their old ground of Les Corts which with a capacity of just 48,000 was too small to accommodate the interest generated by a team led by Hungarian star Ladislao Kubala. The stadium was designed by architects Francesc Mitjans Miró and Josep Soteras Mauri, with the collaboration of Lorenzo García Barbón, and it was constructed between 1955 and 1957, using mainly concrete and iron. Although it was originally going to go under the official name of ‘Estadi del FC Barcelona’, it soon came to be popularly known as the 'Camp Nou' (the ‘new ground’), as opposed to the club’s old home at Les Corts. With a capacity of 99,354, it is now the biggest stadium in Europe. However, the total capacity has varied over the years owing to different modifications. When it was first opened in 1957, it held 93,053 spectators, which would be increased to 120,000 in 1982 on occasion of the FIFA World Cup. However, the introduction of new regulations outlawing standing areas reduced the stadium’s capacity in the late 1990s to just under 99,000.
