Both the earth and humans are made up of 70 per cent water. It permeates everything, keeps everything flowing. What does it mean to us? The exhibition at the Arp Museum presents a history of water with around 50 masterpieces from 1600 to the present day. The special location of the museum on the Rhine and its proximity to the River Ahr also emphasise the relationship between man and nature, which is worth protecting. In the Arp Laboratory in the historic railway station, we are also showing (no) water for everyone. A UNICEF exhibition on water and climate change.
