Parc de la Seille, Urban park in Metz, France

Parc de la Seille is a green space in Metz that runs alongside the Seille River, combining walking paths with planted areas and water features throughout its grounds. The layout includes varied landscapes that support local wildlife and vegetation.

The park opened on 31 May 2002 as parc de la Seille, the first development of the new Amphithéâtre district, built on former wasteland and sports grounds beside the Seille after the river's post-war canalisation. It was designed by architect Jacques Coulon and landscape designer Laure Planchais. In 2016 it was renamed in honour of botanist Jean-Marie Pelt, and since 2012 it has held the Écojardin label.

The park was renamed in 2016 after botanist Jean-Marie Pelt, previously being called parc de la Seille. Its design by Jacques Coulon and Laure Planchais plants vine, mirabelliers and hops in reference to traditional regional crops. Since 2011, open-air METZ PHOTO exhibitions by the Photo-Forum association are renewed every six weeks along the paths.

Six kilometres of paths cross the park, with surfaces matched to use: reused paving stones for walkers, macadam for rollerblades and scooters, stabilised ground for strolling areas. A 700-metre macadam track serves skaters, and a cycle strip runs along avenue Louis-le-Débonnaire from the Lothaire pool to the Arènes forecourt. A metal footbridge installed on 19 December 2011, the passerelle de Graoully, links the park to Queuleu.

The artificial hill at the centre of the park doubles as a lookout over the whole grounds. On it stands Tremblement de ciel, a 25-metre cuproaluminium sculpture covered in gold leaf and weighing 11 tonnes, made in Nantes as one of two identical pieces for the 150th anniversary of the French-Japanese friendship treaty; its twin, La Flamme de la liberté, is in Tokyo.
