Heiligengeistfeld (lit. field of the Holy Spirit) is an area of Hamburg in the St. Pauli quarter. Since 1893 the funfair Hamburger DOM is held here. In times where this area is not used for exhibitions, circuses or the DOM it is a car park. A building from German Telekom, a swimming complex, Millerntor-Stadion, a school, a patrol station, a defensive tower (Flakturm IV) and a supermarket are fixed structures on the field.
The area was named after the homonymous hospital in 1497, forming a kind of green as part of the hospital's endowment to make up for its maintenance. The area has been used for exhibitions since 1863.
With the intensifying Allied bombing of Hamburg the Flakturm IV structure was erected on Heiligengeistfeld starting in 1942 which was a combined anti-aircraft gun tower and air-raid shelter. The massive concrete structure is still standing.
