Arrondissements of the Tarn-et-Garonne department

Administrative role and structure

Each arrondissement functions as an intermediate level between the department and the smallest local units. The chief town of an arrondissement is a subprefecture; when the departmental capital is located in an arrondissement, that town serves both as the department's prefecture and as the arrondissement's subprefecture. Arrondissements are further divided into cantons and communes, which handle local representation and municipal services.

Current arrondissements

• Montauban — the departmental capital; it serves as the prefecture of Tarn-et-Garonne and is therefore also the administrative centre of its own arrondissement. As the prefectural seat it hosts the department's principal administrative services and coordinates policies across the territory.
• Castelsarrasin — the other arrondissement and seat of a subprefecture; it manages state services for its area and acts as a link between local communes and the departmental administration.

Although the department has only two arrondissements today, its internal boundaries and the number of subdivisions have changed over time in response to demographic shifts, reforms and the evolving needs of state administration. The arrangement reflects a balance between centralised functions carried out by the prefecture and more locally focused tasks overseen by subprefectures.

The practical importance of arrondissements lies in coordination: they organise elections, deliver certain public services and collect local statistics used for planning. For residents they are rarely visible as separate political entities, but they remain an essential layer in the hierarchy of French territorial administration, sitting between the department and the network of cantons and communes.
