Black Pencil in the Waterloopbos

On Sunday 30 August 2026, the Waterloopbos in Marknesse will provide the setting for a special concert. Alongside the impressive landscape artwork Deltawerk//, the Black Pencil ensemble will perform an exclusive open-air concert. They will perform TIJ, a new composition by Celia Swart, for the first time at the site of the artwork itself. This work is inspired by Deltawerk//. You will also hear pieces from Black Pencil’s extensive repertoire, featuring music from different centuries and countries.

After the concert, you’ll set off with the forest ranger on a walk through the Waterloopbos. You’ll discover the fascinating history of this former hydraulic engineering laboratory, where researchers spent years experimenting with harbours, rivers and delta works. In the forest, you can clearly see just how quickly nature works. Many of the models have been overgrown by mosses, plants and trees. All these elements give the Waterloopbos a fairytale atmosphere. A forest where a surprise awaits around every bend.
