Set in the high bocage of the Vendée, the village of Monsireigne offers a hilly, wooded landscape, despite the impact of agricultural consolidation. The commune stretches across a plateau formed by the Grand Lay, offering a diversity of topography and ecology. The purpose of this in-depth analysis of the commune of Monsireigne is to highlight its strengths and weaknesses in order to design a forward-looking urban study aimed at revitalizing the town center. This mission should enable the commune, its elected representatives and its residents to envisage the future of the town center, to project themselves in a desirable, coherent and sustainable urban project that is both technically and financially realistic.
