Sanctuaire de Notre-Dame de La Peinière, Marian chapel in Saint-Didier, France.

The Sanctuaire de Notre-Dame de La Peinière is an octagonal chapel with neo-Romanesque design built between 1895 and 1900. It features buttresses and small apses on the outside, while stained glass windows by Felix Gaudin decorate the interior space.

A farmer discovered a statue of the Virgin Mary in the 16th century while plowing his field. This discovery led to the building of a sanctuary and eventually the construction of the chapel we see today.

The hamlet was recorded as Poinière or Painière on old maps; the clergy reshaped the name into La Peinière to make the Virgin honoured here Notre-Dame de la Peine, consoler of the afflicted. The stained glass of the apse and apsidal chapels is by the glass painter Félix Gaudin. The main pilgrimage is held in early September for the Nativity of the Virgin.

The chapel stands in the hamlet of La Peinière, northeast of Saint-Didier and near the Vilaine. The main pilgrimage gathers in early September for the feast of the Nativity of the Virgin, when Notre-Dame de La Peinière is honoured as patroness of the archdiocese of Rennes, Dol and Saint-Malo.

The hamlet was recorded as Poinière on the Cassini map and as Painière on the 1830 cadastral plan; the clergy reshaped the name into Peinière to make the Virgin honoured here Notre-Dame de la Peine, consoler of the afflicted. The prayer approved by Archbishop François Saint-Macary on 2 February 1999 addresses her under that title.
