"The Sechseläuten is a traditional spring holiday in the Swiss city of Zürich celebrated in its current form, on the 3rd Monday of April, since the early 20th century. Following the parade of the Zünfte (guilds), the climax of the holiday is the burning of Winter in effigy, in the form of the Böögg, a figure of a snowman prepared with explosives(wikipedia).
They really take the end of winter very seriously :)
