Saint-Jean-Trolimon has 2 chapels.
The chapel of Saint-Evy nestles at the bottom of the valley, at the foot of the reed bed, in a bucolic setting reflected in its stained glass windows.
The chapel, which originally consisted of a single nave, has taken on a T shape over the centuries: it is a single nave ending in a flat apse intersected by a transept. The gable of the north transept bears a stone marked with a chalice and the date 1660, probably indicating the extension work that added the transept to the original nave. The walls of the oldest part are made of rough rubble stone, whereas the 17th-century part is of fine ashlar. The junction of the new walls is visible at the chevet between the nave and the transept, revealing the different construction periods.
To the east, a modest Gothic-style skylight with two compartments illuminates the choir. A stream runs through the chapel beneath the choir and fills the fountain in the south wall. The chapel has superb stained glass windows created by Guy Trevoux (2007).
A small openwork bell tower crowns the west entrance door. It is made up of four levels demarcated by slight cornices. A new bell was installed in its chamber in 2001, christened Marie-Anne, it rings in F sharp.
During the French Revolution in 1796, the chapel was sold to Jean-Marie Pierre Le Bastard de Kerguifinec, who preserved it and sold it back to the commune of Saint-Jean in 1816. It was reopened to worship in 1817 by royal decree.
