Oktoberfest (German pronunciation: [ɔkˈtoːbɐˌfɛst] ; Bavarian: Wiesn, Oktobafest) is the world's largest Volksfest, featuring a beer festival and a travelling carnival, and is held annually in Munich, Bavaria, from mid- or late-September to the first Sunday in October. The annual event attracts more than seven million international and national visitors at its peak. Locally, it is called d'Wiesn, after the colloquial name for the fairgrounds, Theresienwiese. Oktoberfest is an important part of local culture, having been held since the year 1810 (with intermissions).
