A flamboyant Gothic church, Notre-Dame du Folgoët is a major building of 15th century Breton architecture whose fame extends well beyond Léon. This monument, witness to the history of an entire country and its inhabitants, has seen great names pass through its walls (Anne of Brittany, François 1st, etc.). A spiritual center, particularly at the time of his famous pardon, this basilica also has undeniable architectural, cultural and even political and economic importance. Its popularity also owes a lot to the many mysteries that surround it and which make this religious building a unifying heritage of the Coast of Legends.

The church dates from the 16th and 17th centuries, while the fountain dates from the 18th century. The transept bears the date 1577. The porch, dating from 1623, offers the particularity of a continuous arched gallery that surmounts the entrance arch and gives access to an archive chamber above the porch. The full-arch opening of the porch, next to two fluted columns with Corinthian capitals, is crowned by a frieze surmounted by a gallery with openwork stone railing. The pediment is attenuated by the bell tower and is dug by a niche which houses the statue of Our Lady. The bell tower dates from 1715. The cemetery houses the Gothic ossuary. Leaning against a wall and dated 1656, the fountain is crowned by a niche containing a statue protected by a canopy. Source: https://monumentum.fr/eglise-notre-dame-pa00090476.html
