The Striezelmarkt in Dresden is one of the first genuine Christmas markets in the world. Founded as a one-day market in 1434, it celebrated its 585th anniversary in 2019. Its 240 stands attract about 3 million visitors from all over the world. The annual market lasts throughout the Advent season until Christmas Eve.
This market event was first mentioned in 1434, under Friedrich II, Elector of Saxony, when it was held the Monday before Christmas on the Altmarkt square. Originally, it was a one-day market to provide the citizens of Dresden with the sale of meat for the Christmas meal after the traditional Advent period of fasting.
