The date of the chapel's foundation is still unknown, but it wasn't until 1029 that we heard mention of this "monastela" in the deed of gift from Alain Canhiart, Count of Cornouaille, to the Abbey of Sainte-Croix.

Houses in Lothéa were burnt down during the League Wars by the notorious brigand Guy Eder de La Fontenelle.

[3] It wasn't until the rector Jean Cariou, two centuries later, that the ancient sanctuary was restored to the form we knew before its complete ruin.

This territory, covered with trees and bushes, offers a view of the Carnoët forest, which belongs to the King, valleys, mountains, farmland and meadows.

The river Laïta crosses this territory, which contains the noble houses of Rosmain-Glasse [Ros-an-Menglaz], Kerlidu and Quelbin [Queblen]On the eve of the Revolution, the parish was very poor; it included the trève de Trélivalaire.

In 1791, the Quimperlé municipality decided to suppress the parish, despite protests from parishioners, following the rector's refusal to take the oath of loyalty to the Civil Constitution of the Clergy.

[11] In 1869, Ernest du Laurens de la Barre [fr] wrote a story about this grand pardon.

[12] Abandoned in 1947, the church collapsed ten years later, becoming a stone quarry, with only the gable and bell tower remaining.

Three small skylights in the roof provided diffused light in the main nave, creating an atmosphere conducive to contemplation.

Two engaged half-columns to the east and west support five ogival arches whose mouldings penetrate directly into the columns without capitals.

Only the molded arches, the surrounding stones and the niche above it bear witness to its origins in the time of Recteur Cariou.

A wooden St Théa preserved in the church of Notre-Dame de Quimperlé joins this group of statues.

The other statues date back to the 17th century: the large Christ is also in Notre-Dame, while the Eternal Father is currently in the Abbey church of Sainte Croix.

These are two low, flat stones that prevent stray animals from entering, but allow access to the chapel without having to open the gate.
