A Fortress Reclaimed by Nature

The story of Wolvenberg begins in 1859, when Antwerp's great Brialmont belt of fortifications encircled the city. This particular section, known as Front 8, featured a glacis and a defensive moat between two now-demolished barracks. When the military grounds were demilitarised in the 1930s, local youth groups — including scouts whose youngest members were called "wolf cubs" — claimed the land as playground territory, and it became known colloquially as the Wolfjesberg. The name later hardened into the more rugged-sounding Wolvenberg under the influence of a motorcycle club that used the grounds as a training track.↗

In 1963, the construction of Antwerp's ring motorway sliced through the old ramparts, leaving the terrain rough, disturbed, and largely forgotten. But nature had other plans. Spontaneous vegetation took hold: willow scrub colonised the damp depressions, poplars were planted on the western edge, and a rich undergrowth emerged on the limestone-rich soil exposed by the fortification works. By the 1990s, nature enthusiasts had discovered what was quietly growing in this urban no-man's-land and formed a working group to protect it. Wolvenberg was officially designated a nature reserve on 11 December 2001.↗↗

What to See on the Walk

The marked nature trail covers roughly 1.4 kilometres and can be enjoyed in about twenty minutes at a leisurely pace. The main entrance sits at the corner of the Binnensingel and Posthofbrug, just behind Berchem station, where a quiet path called the Wolvenbergpad also leads up from the pedestrian bridge connecting Villegaspark to Brilschanspark.↗↗

The reserve's topography — shaped by old earthworks and the excavations for the motorway — creates genuine height differences in a very compact area. On the higher slopes you'll walk through stands of elm, while lower ground holds ash, crack willow, English oak, and field maple. Beneath the canopy, thickets of hazel, blackthorn, red dogwood, and elder provide structure and berries. In spring the herb layer bursts into bloom with garlic mustard, yellow tormentil, and wild carrot; mowed railway verges nearby add ox-eye daisy and field pennycress to the palette.↗↗

The old defensive moat is now a pond fed by the Zilverbeek, surrounded by a humid willow carr dotted with smaller pools. Remnants of lime-mortar brick walls from the original fortifications still emerge from the vegetation — a subtle reminder that this is a military landscape being slowly, beautifully digested by the wild.

Wildlife in the City

For such a small site, Wolvenberg's wildlife list is remarkable. Birds of prey nest here: the sparrowhawk and the dashing little hobby falcon hunt among the trees. Kingfishers flash along the water edges, and grey herons stalk the deeper pond. The water hosts frogs, toads, and salamanders — including both smooth and alpine newts — while foxes and polecats visit from the wider green belt.↗↗

The reserve is nationally important for its mollusks. Among the rich community of snails and slugs are species not seen alive in Belgium since the 1950s, along with critically threatened ones like the thick-shield snail and the broad-ribbed glass snail. Around the pond, lichens and mosses flourish on old wood, and nearly 200 species of fungi have been recorded. An underground bomb-proof vault — a remise from the fortification era — has been repurposed as a bat roost.↗↗

Getting There and Practical Tips

Wolvenberg is one of the easiest urban nature reserves to reach. Antwerp-Berchem station is a stone's throw from the main entrance. By bicycle, the area sits on the Brialmont cycling route — a 40-kilometre loop connecting all the forts that once guarded the city — with the Nachtegalenpark and Rivierenhof gardens linked via the adjacent cycle path. The reserve is free and open year-round.↗

Dogs are welcome on a leash. Sturdy shoes or boots are recommended, especially in winter when paths can be muddy. The ground is uneven and the trail passes through genuine scrub and wet areas, so this is a nature walk rather than a manicured park stroll.↗

Natuurpunt Antwerpen Stad volunteers organise themed guided walks throughout the year — tree walks, nettle-tasting strolls, and seasonal excursions — all starting from the main entrance at Posthofbrug. Booking a private guided visit for a group is also possible. The management team works weekly to keep the area biodiverse: mowing, maintaining the path, building brush piles for wildlife, and removing invasive species.↗↗

Part of a Larger Green Belt

Wolvenberg sits within a chain of urban green spaces known as the Ringbos and the Groene Singel project, forming a vital ecological corridor linking habitats around and across the motorway. To the south across the R1 lies the Brilschanspark; to the north across the Binnensingel is Villegaspark. Plans are underway to further connect the reserve with surrounding parks and, if parts of the ring road are ever capped, to expand this green network even more.↗↗

The reserve also provides essential ecosystem services for a densely built neighbourhood: cooling the urban heat island, buffering stormwater, and offering a rare accessible green space that supports mental wellbeing in a heavily paved area. It's proof that even amid motorways and railway lines, a determined patch of wild Belgium can thrive.↗
