Mesnil-Roc'h

Mesnil-Roc'h covers 141.16 square kilometers with 4,457 residents, featuring rolling countryside terrain between 34 and 99 meters elevation in the northwestern French region of Brittany.

The commune was officially established on January 1, 2019, through the administrative merger of three former municipalities: Saint-Pierre-de-Plesguen, Lanhélin, and Tressé, creating a new territorial entity.

Local heritage includes the 15th and 16th-century Saint-Pierre church and the Maison des Feins dolmen, reflecting centuries of Breton cultural traditions and architectural development in the region.

The town hall located at 6 place de la Mairie in Saint-Pierre-de-Plesguen provides administrative services to residents, using postal code 35720 and INSEE code 35308 for official procedures.

This newly formed commune combines the French term 'mesnil' meaning rural domain with the Breton word 'roc'h' signifying rock or height, reflecting its bilingual regional heritage.
