Tournebu is a former French commune in Calvados, located in northwestern France. It was part of the historical region of Basse-Normandie, a name that is still often used for the area’s regional identity even though the modern administrative region is Normandy. Like many small rural communes, Tournebu formed a local administrative unit with its own municipal council before being merged into a larger commune.
The name now refers to a place within the new commune of Cesny-les-Sources. On 1 January 2019, Tournebu lost its independent commune status and was incorporated into this new administrative structure. Such mergers are common in France, where small communes are sometimes combined to simplify local government, improve shared services, and strengthen administrative coordination.
Administrative background
In France, a commune is the smallest unit of local government. Communes can be large cities or very small villages, and many rural communes have limited populations and resources. Over time, national and local reforms have encouraged the creation of communes nouvelles, or new communes, which bring several former communes together while preserving local identity through delegated arrangements in some cases.
Place in the region
Tournebu belongs to a part of Calvados shaped by rural settlement, agriculture, and the long administrative history of Normandy. The surrounding landscape is typical of many inland areas of the department, where small villages and parish-based communities developed around farmland and local roads. Although Tournebu no longer appears as an independent commune in current administration, it remains a geographic and historical locality.
- Status: former commune
- Department: Calvados
- Historical region: Basse-Normandie
- Current commune: Cesny-les-Sources

Tournebu is therefore best understood as part of the broader story of French local administration: a small rural commune that was reorganized into a larger municipal entity, while its name continues to identify the locality and its heritage.
