An apple tree stands in Vieren's geographical centre. The Viersen artist Jürgen Vossen implemented a labyrinth around the apple tree.
The labyrinth is situated at the edge of the Süchtelner Heights, in close proximity to the sports park and large playing fields. The area of the labyrinth measures around 2500 square metres. It was designed with boulders in the classic form of a 'Cretan labyrinth' - square with seven cycles.
