It does exactly what it says on the tin. Kassel’s annual Spring Exhibition celebrates the end of winter and the arrival of spring, a time when flowers bloom and the temperatures begin to rise, otherwise known as the very best time of the year. Flowers, insect world (not as creepy as it sounds) and cultural workshops are the name of this game, a festival that is as exciting for young folks as it is engaging for the elderly. A great way to blast away those winter cobwebs.
