Can Liège’s new Katherine Johnson park give the Longdoz the green space it lacked?
Liège officially inaugurated the 4,400-square-metre Katherine Johnson park on 22 August, turning the former Palmolive industrial site in the Longdoz into a public space with 46 trees, play areas and an interactive fountain.
The project gives a densely built Liège neighbourhood an accessible place for shade, play and social contact while demonstrating how Walloon urban funding can return an abandoned industrial parcel to public use.
officially inaugurated the on Saturday, 22 August, completing the conversion of a former industrial site in the into a 4,400-square-metre public green space. reported that the former industrial wasteland transformed into a park now contains 46 trees, while local outlet confirmed that the site, at 79 rue Lairesse opposite place Baugniet, had already been open to the public since 10 July.
For residents, the immediate gain is unusually tangible: somewhere to sit, play and cool down in a densely built neighbourhood that had little accessible greenery. According to the project information relayed by #Liégeois, the park combines a central lawn, picnic tables, drinking water, paths, loungers, climbing and sliding structures, and a playful fountain whose jets can be activated on demand. Two murals connect the landscape to ’s cultural life: one was produced by the Belgian collective Atelier Louves, and another by young people from Latitudes Jeunes working with the Liège-based association Spray Can Arts.
The transformation cost €2 million and was fully subsidised by the through its urban-development programme, reported. That makes the park a Walloon policy intervention as well as a municipal amenity: regional money has replaced a long-disused private industrial footprint with public land intended for recreation, neighbourhood events and informal social contact. The site’s gates are scheduled to close at 20:00 in summer and 17:00 in winter, a restriction the city presents as necessary to protect the facilities.
The once combined factories, railway infrastructure and working-class housing, but industrial decline left gaps in its urban fabric. ceased operating on this site during the 1980s, according to #Liégeois, and acquired the land in 2018. Residents, neighbourhood organisations and municipal services began discussing its future in 2019 through three participatory workshops. The pandemic interrupted face-to-face work, but the ’s own account shows that contacts continued before construction began in June 2024.
The park’s name adds an international note without changing the essentially local character of the story. ’s municipal council approved the name in 2023, honouring the African-American mathematician whose trajectory calculations supported NASA missions. The neighbourhood committee argued that explaining Johnson’s life could encourage girls to imagine themselves in scientific careers. That is a specifically Liège-centred use of an American legacy, not an attempt to turn a neighbourhood redevelopment into a US story.
The broader European significance lies in what this modest project represents. The says lower-income urban communities typically have less access to good-quality green space, while parks and trees can provide shade, support health and create places for exercise and social contact. The European Commission’s Urban Nature Platform similarly urges cities above 20,000 inhabitants to develop accessible, biodiverse parks and other green infrastructure. ’s project was not identified as EU-funded, but it follows that wider European direction: recovering developed land instead of consuming a fresh site, adding tree cover and involving residents in the design.
There is nevertheless a useful tension between the official and neighbourhood readings. Works alderman Roland Léonard, a Socialist municipal politician, described the park during construction as something that would be “offered to the neighbourhood.” The -Boverie committee places greater emphasis on continuing local responsibility, writing that public spaces are also “under our responsibility” if they are to remain enjoyable. Its account records concerns about illegal dumping on the former wasteland and, nearby, requests for more facilities for teenagers. A completed park therefore settles the land-use question, but not every question about maintenance, age-inclusive programming or the distribution of green space across .
Attention now shifts from construction to use. The city will need to maintain the young trees, fountain, play structures and murals, while residents and associations test whether the space can sustain neighbourhood celebrations, outdoor culture and everyday recreation without creating friction for adjacent homes. No public post-opening evaluation, visitor estimate or detailed long-term maintenance budget has yet been identified. Those measures—not the inauguration photographs—will show whether this ancienne friche industrielle transformée becomes a durable shared place.
Impact
Regional — The park is a concrete Walloon urban-regeneration project: the Walloon Region financed the works through its Perspective de développement urbain, while Liège will operate and maintain the site.
Local — Longdoz residents now have a 4,400-square-metre public park on a former industrial parcel within their Liège neighbourhood. Its 46 trees, lawns and seating provide places for shade and social contact, while play structures and interactive water jets serve children and families. Visitors can also use a drinking fountain and view two murals. The City of Liège is responsible for operating and maintaining the space, making its upkeep a continuing municipal service rather than a temporary redevelopment intervention.
What it means for you
The park is already open, so residents and visitors can use it without waiting for further construction or another launch date. Families can access play structures and interactive water jets, while other visitors have lawns, seating, shade and a drinking fountain available on site. There is no announced admission charge or application process in the supplied material. People planning a visit should distinguish the public opening on 10 July 2026 from the formal inauguration on 22 August. Questions about access, maintenance or facilities should be directed to the City of Liège, which operates the site.
Opposing perspectives
- Liège municipal and Walloon investment view
Works alderman Roland Léonard described the project during construction as a park that would be “offered to the neighbourhood.” The municipal framing stresses delivery: regional funding has converted an abandoned industrial site into a protected, multipurpose public amenity.
- Longdoz-Boverie residents’ stewardship view
The neighbourhood committee welcomes the park but frames it as a continuing civic responsibility, writing that public spaces are also “under our responsibility” if they are to remain enjoyable. This view shifts attention from inauguration to maintenance, cleanliness and whether programming serves different age groups.
