Église et enclos paroissial Saint-Pierre-et-Saint-Paul

The parish enclosure in Ploulec'h contains a collection of works dating from between the Iron Age or Gallo-Roman period and the 1st quarter of the 20th century, the earliest dating being provided by the presence of a Gallic stele or a milestone integrated into the enclosing wall.

The church, the cross and the cemetery boundary wall were included in the Supplementary Inventory of Historic Monuments on 31 March 1926. The boundary wall includes a cemetery, a calvary and an ossuary.

The parish church of Saint-Pierre-et-Saint-Paul was built in two phases. Architectural analysis suggests construction during the 1st half of the 16th century, probably by the workshop of Philippe Beaumanoir, followed by a reconstruction campaign during the 2nd and 3rd quarters of the 18th century. The bell tower was rebuilt in 1738 (date recorded), and the south aisle and porch were rebuilt in 1755.

The remains of an ogival vault forming the initial covering of the south porch attest to a primitive construction contemporary with that of the church.
