For three weeks, 45 international artists will exhibit around 140 works of contemporary glass art and extraordinary installations. More than 75 works of art will be on display in the public parks of the city of Munster. The trees, meadows and the course of the river Örtze, the historic buildings of the Ollershof and the natural wetlands offer impressive exhibition spaces through the influence of light and shadow as well as wind and water. Admission is free.
