In the page's words:

The DEICHBRAND Festival on the North Sea takes place in July in Cuxhaven/Nordholz. Every year, 60,000 visitors come to see more than 120 national and international acts. They play on six stages over four days and provide the perfect summer highlight alongside a sophisticated supporting program! All guests can camp on site from Wednesday (early arrival) to Monday lunchtime and, thanks to the huge food line-up, workshop area, pool with beach area, Action World and the Talking Trees oasis of peace, can look after themselves and experience a very special break from everyday life. All information about the festival can be found at deichbrand.de!
