From 1946 to 1961, FC St. Pauli played near a ground that was dismantled before the 1963 garden exposition. A new ground was under construction, but it faced delays, opening only in 1963 due to drainage oversights that turned the pitch into a swamp after rainfall. Since then, the club has remained at this location, but the stadium underwent various changes, including changes in name and structure. Seating was added, and capacity decreased for safety reasons, hitting a low point of 19,800 in 2005. Major redevelopment efforts began in the 2000s, with the South stand and a new main stand opening in 2010 and 2013, respectively, raising capacity from 24,500 to 29,000.
The north end was the last grandstand replaced in 2015, though capacity saw limited growth. The stadium boasts unique features, such as a miniature railway model delivering drinks to viewers and a freestanding skybox. While known for its alternative culture, it also leads in some aspects, including a club-led kindergarten and a catering menu with vegetarian and vegan options.
