Theresienwiese is an open space in the Munich borough of Ludwigsvorstadt-Isarvorstadt. It serves as the official ground of the Munich Oktoberfest. The name of the site is derived from the name of Princess Therese of Saxe-Hildburghausen, the wife of Crown Prince Ludwig I. Their wedding took place on Theresienwiese in 1810. 

A space of 420,000 square metres (4,500,000 sq ft), it is bordered in the west by the Ruhmeshalle and the Bavaria statue, symbolizing the State of Bavaria, and in the east by Esperantoplatz, a square named for the international language Esperanto. There, a memorial commemorates the victims of the 1980 Oktoberfest bombing. 

Bavariaring, an orbital road, provides access to visiting traffic. In the north the towers of St. Paul are visible.

Since then, the Oktoberfest is celebrated every year to commemorate this event. In addition to the Oktoberfest, a spring festival and a winter festival ("Winter Tollwood") take place there as well. Every year in April, one of Germany's largest flea markets is also held there.
