In Brussels, some of the most beautiful green spaces are worth seeking out. Hidden behind an almost unmarked gate on Chaussée de Wavre, the Jean-Félix Hap Garden embodies the art of secrecy… Discover this romantic, peaceful, and delightfully timeless park in the heart ofEtterbeek.
A hidden retreat in the middle of the city
You have to know it’s there! From the street, there’s almost nothing to suggest what lies behind the walls of the Jean-Félix Hap Garden. And yet, once you step through the small gate, the atmosphere changes immediately. The sound of traffic fades away, replaced by birdsong, the rustling of leaves, and the gentle lapping of the pond. With its expansive lawns, winding paths, and shady spots, the park makes you feel as if you’ve left Brussels behind. That’s precisely what gives it its charm: that rare sensation of discovering a place that’s still unspoiled, almost a hidden gem. And all this, just a few minutes from the European Quarter and the hustle and bustle of the city.
A garden steeped in history and poetry

The site ’s history is as fascinating as its setting. First mentioned as early as the 16th century, the property once housed a FlemishRenaissance-style castle, of which only a few romantic remnants remain today. In the 19th century, the Hap family transformed the estate into a private garden, complete with an orangery, a gazebo, and an elegant neoclassical house at the park’s entrance. It wasn’t until 1959 that Jean-Félix Hap agreed to open it to the public, offering the residents of Etterbeek this little green treasure that had long been hidden behind its walls. As you stroll past the ruins, the natural pond, or the former orangery, you quickly understand why the place still inspires writers, photographers, and Sunday strollers.
Biodiversity, remarkable trees, and a spring-like atmosphere
But the Jean-Félix Hap Garden isn’t just appealing for its romantic charm. The park also plays an important ecological role in the capital. A remnant of the former Maelbeek Valley, it is home to an astonishing level of biodiversity for an urban space. Aquatic plants, birds, small freshwater crustaceans , and even three-spined sticklebacks live in the pond fed by a former stream. Everywhere, the vegetation bursts into life in the spring. Poplars, maples, black locusts, purple beeches, and Virginia tulip trees make up a veritable open-air botanical collection. The Virginia tulip tree, with its impressive trunk, is even listed among Brussels’ remarkable trees! It’s the perfect place to slow down, breathe… and forget for a few moments that you’re right in the middle of the city.
