Loir en Vallée

Loir en Vallée (, literally Loir in Valley) is a commune in the department of Sarthe, northwestern France. The municipality was established on 1 January 2017 by merger of the former communes of Ruillé-sur-Loir (the seat), La Chapelle-Gaugain, Lavenay and Poncé-sur-le-Loir.

Ruillé-sur-Loir was the first home to the Brothers of St. Joseph, now the Holy Cross Brothers associated with Notre Dame University in the USA.
