Communes of the Ille-et-Vilaine department

Purpose and responsibilities

Each commune is governed by a municipal council and a mayor elected by residents. Typical responsibilities include civil registration (births, marriages, deaths), primary school management, local planning and permitting, maintenance of communal roads and public spaces, and delivery of basic social services. The scale of services varies greatly with population and resources.

History and development

Communes were established during the French Revolution as standardized local units to replace older feudal jurisdictions. Over time Ille-et-Vilaine’s communes have adapted through intercommunal cooperation and occasional mergers. Recent reforms encourage voluntary grouping into intercommunal bodies to manage shared infrastructure, economic development and environmental planning.

Administration and how to use the list

Each commune is identified in national registers by an INSEE code and postal code. For planners, genealogists or visitors, the communal list is a practical tool: it shows local boundaries, points of contact and links to intercommunal organizations.

The official list of communes provides the authoritative names and current municipal arrangements.
