In Winterswijk, right next to an active stone quarry, there is another quarry that is no longer in use and where every year since 2002 a pair of Eurasian Eagle-Owls breed in the rock face of the quarry.
Every year, the Owls attract many interested viewers to the quarry, which in the past sometimes led to disruption.
For a number of years now, a large wooden viewing wall has been placed from which the Owls can be observed without disturbing them.
