Quai Turenne, Riverfront promenade in central Nantes, France.

Quai Turenne is a paved pedestrian promenade on the Île Feydeau in central Nantes, along the filled-in Bras de l'Hôpital. A low stone edge separates the light grey paving from a grass strip about thirty metres wide, planted with a few trees and shrubs. Raised footways continue the lines of rue Du Guesclin and rue Bon-Secours towards boulevard Jean-Philippot.

The waterfront was named after Henri de La Tour d'Auvergne, Viscount of Turenne, a 17th-century French military leader. During the 1920s and 1930s, the old river channel was filled in to create this walking area.

The quay's name honours Henri de La Tour d'Auvergne, Viscount of Turenne, Marshal of France, killed at the Battle of Salzbach on 27 July 1675. Before taking this name it was successively called quai Bon-Secours, quai de Saxe, quai Lowendal, quai Valleton and quai Villestreux. The paved surface and the grassed strips about thirty metres wide, crossed by raised footways, recall the Loire channel that once ran here.

The paved promenade is reserved for pedestrians and two-wheelers, with raised pedestrian crossings continuing the lines of rue Du Guesclin and rue Bon-Secours towards the sidewalks of boulevard Jean-Philippot. Between the walkway and that boulevard lie about thirty metres of lawn planted with a few trees and shrubs, crossed by those crossings.

The promenade sits where the Loire once flowed before the river shifted its course and reconnected to the city. Walking here means treading over ground that once lay beneath the water's surface.
