In the year 1810, on October 12, the first Oktoberfest was held. It lasted for five days and was intended to commemorate the union of Princess Therese von Sachsen-Hildburghausen and the Bavarian Crown Prince, who would later become King Ludwig I. It later developed into an annual celebration with an agricultural fair, live music, and food stands. As time went by, booths evolved into beer halls, and nowadays, brewers construct transient constructions that can accommodate up to 6,000 people.
