On 12 October 1810, Crown Prince Ludwig of Bavaria married Princess Therese of Saxe-Hildburghausen. Munich officials invited the public to celebrate on fields outside the city walls. The site was named Theresienwiese (“Therese's Meadow”) the following year and is still called Wiesn. Oktoberfest (Bavarian: Oktobafest/d'Wiesn) is the world's largest Volksfest. It combines a beer festival with a funfair and is held annually in Munich on the Theresienwiese from mid-September to the first Sunday in October.
