The Hertha-Stadion in Gesundbrunnen was inaugurated in February 1924 with a league match against VfB Pankow. It became famous under the nickname Die Plumpe — Berlin slang for water pump, after the pumps that lined the surrounding streets. The ground held up to 35,000 spectators and became the home of Hertha's most successful pre-war era under Hanne Sobek.
