Renaturation du cours d’eau « Pétrusse »
Rue Saint Ulric
2651 Luxembourg

The renaturation of the "Pétrusse" in Luxembourg is an ambitious program aimed at restoring and improving the natural environment of its valley. The main objectives of the project are: improving biodiversity by creating natural conditions for the watercourse, which will encourage the return of local fauna and flora; reducing the risk of flooding by allowing the water to flow more slowly; enhancing the quality of life by transforming the valley into an attractive green space with hiking trails, bike paths, playgrounds, and recreational facilities; adapting to climate change by improving the ecological balance and increasing the valley's resilience to extreme weather events. The first phase of the project, carried out between 2020 and 2024, has already shown positive results, with the return of aquatic life and a notable improvement in the ecosystem. The second phase, which will begin in the spring of 2025, will focus on extending the work towards Hollerich.
