Camp Nou — Barcelona, Spain

Camp Nou is the largest stadium in Europe at 99,354 capacity, home to FC Barcelona since 1957. It is currently undergoing the Espai Barça renovation — a €1.5 billion project that will create a covered 105,000-seat arena with a translucent roof designed by Fenwick Iribarren. The ground has hosted the 1982 World Cup, the 1989 and 1999 Champions League Finals, and countless iconic European nights. Its sheer scale — the upper tiers seem to scrape the clouds — creates a visual spectacle unique in world football.
