Puyenbroeck, Provincial domain with ponds and forest in East Flanders, Belgium

Puyenbroeck is a 510-hectare provincial domain in East Flanders, mostly in Wachtebeke with parts in Zaffelare and Eksaarde. It is low-lying with several large ponds, and the area south of the Zuidlede is more forested. The domain includes Puyenbrug Castle, a 10-hectare play forest, a 23-hectare animal park, and about 150 hectares of forest.

The Province of East Flanders bought the area in 1965 and opened it to the public in 1969. In 2017 and 2018 it hosted Music For Life, the charity event of Studio Brussel. Between 2019 and 2021 the 50-hectare Landschapspark was laid out, linking the former flower park to the animal park with new paths and a 120-metre suspension bridge; this redesign won the Prijs Publieke Ruimte 2023 in the rural projects category.

The name combines "Puy", an artificial elevation, and "broeck", the marshy character of the meadows. Spelling reforms produced variants such as Puienbroek and Puienbrug, and Puyenbroeck also survives as a Belgian surname (Van Puyenbroeck) and in street names like the Puienbroeklaan in Bruges. The domain hosts events including Music For Life in 2017 and 2018 and the Ambiancecross cyclo-cross race in 2018 and 2019.

The domain can be entered from several points across its three municipalities, each with parking nearby. The ground can get muddy after rain, so sturdy footwear is a good idea, especially on forest paths.

A former ice cellar in the domain has been converted into a winter roost for bats. The park also has a permanent nesting wall used by sand martins and bee-eaters, and shallow spawning beds were created in the ponds for fish.
