Signal Iduna Park — Dortmund, Germany

Signal Iduna Park is home to Borussia Dortmund and holds 81,365 spectators — the largest stadium in Germany. Its Südtribüne (Yellow Wall) is the largest standing terrace in European football, holding 24,454 fans who create a noise level that has been measured at 130 decibels. The atmosphere on European nights against Real Madrid or Manchester City is considered by many football journalists as the most intense in world football. Opened in 1974 and expanded five times, it generates 55,000 season ticket holders for 81,000 seats — meaning tickets for regular visitors are almost impossible to source.
