Tens of thousands of revelers marked the opening day of the 189th Oktoberfest. The celebration began Saturday and runs through Oct. 6 in 18 large tents covering the fairground.

The festival takes place in Munich every year, at Theresienwiese, a 100-acre fairground space in the city’s Ludwigsvorstadt-Isarvorstadt district, near the Old Town. Believe it or not, Oktoberfest isn’t actually considered a beer festival in Germany – instead, it’s a folksy celebration popular among families as well as those after a stein or two.
