The Jardin des Plantes district, on the northern seafront of Saint-Nazaire. Google Maps.
The Jardin des Plantes district is laid out on the northern seafront of Saint-Nazaire, between the rue de Pornichet and the boulevard du Président Wilson, at the foot of the centre. It takes its name from the landscaped garden created in 1886 by the landscape designer François Aubry at the town's request, a seafront garden open to the shore.
The garden, of around two hectares, presents species native to the coast and Mediterranean varieties, a rose garden and a pergola that adorns its main walk. That seafront green space, together with a children's playground, shapes life in the area and gives it the identity of a residential district close to the beach.
The housing stock mixes apartment buildings and houses facing the seafront, in an area sought after for its setting. The immediate proximity of the shore and the garden explains a high price level, among the highest in the town after the western coast.
