L'Immaculée is a district in the north of Saint-Nazaire, a former country village that became part of the town. Nicknamed the countryside in the town for its many green spaces, it keeps a leafy identity of detached houses, away from the centre.
The Bois-Joalland lake, a body of water of around forty hectares below the district, is its main landmark. Created during the Second World War, it long served to supply the area with water and today hosts walking, fishing, running and water sports, with a path of about three kilometres running around it.
The housing stock is made up mainly of individual houses in a suburban setting that respects the neighbouring woodland. That residential, green character, together with the reputation tied to Bois-Joalland, makes L'Immaculée a sought-after northern area, dominated by houses.
L'Immaculée attracts above all families looking for a house with land in a quiet, leafy setting, along with buyers seeking the proximity of the Bois-Joalland lake and its outdoor activities.
