Lemmi alias Schlumpf
July 4, 2026, Chapelle Saint-Guirec

The Oratory of Saint-Guirec was built in the 12th century on the beach where, according to legend, Saint Guirec landed from Wales in the 6th century. He is said to have sailed in a granite trough. However, his arrival in a curragh, a boat made of wooden slats covered with leather, is historically documented. The trough proved extremely useful on board, serving as ballast, a hearth, and a storage container. Over the centuries, legends arose about Breton saints, based on more or less verifiable facts and Celtic traditions, which were later adopted by the Church. Inside the oratory is the granite statue of Saint Guirec. Young girls would come and stick a needle into it, and if it got stuck, they would get married within a year. Saint Guirec was also invoked to help children learn to walk by placing them in the Gwele of Saint Guirec, a hollow rock behind the Calvary.

Saint-Guirec beach is picturesquely situated among the pink granite cliffs of the Côte de Granit Rose (Pink Granite Coast). Highlights include the Saint-Guirec Oratory on the beach with its marriage legend, a small chapel nearby, the Château de Costaérès offshore, and the GR34 coastal hiking trail, which runs directly along the beach and offers spectacular views.

The Oratory of Saint-Guirec dates back to the 12th century. A statue of Saint Guirec is housed in a small niche. For centuries, women, especially, have made pilgrimages here to pray for their husbands' safety at sea or to wish for a husband. According to an old tradition, unmarried women place a pine needle in the statue's nose; if it remains stuck during the next high tide, it is considered a sign of an impending wedding. The original 14th-century wooden statue was moved to the Chapel of Saint-Guirec in 1904, while the granite statue that replaced it was partially damaged in 1934.

The Chapelle Saint-Guirec is a small Romanesque church dating back to the 12th century. According to legend, it was built on the spot where Saint Guirec landed in the 6th century to spread Christianity. The chapel contains the original 14th-century wooden statue of the saint, which once stood in the oratory. It has been a destination for pilgrims for centuries.

The fine sandy beach slopes gently into the turquoise sea, inviting you to linger. At low tide, a fascinating mudflat area is revealed. On the shore stands the small oratory of Saint-Guirec, a chapel to which pilgrims have flocked for centuries to pray for the safety of sailors or to seek a husband. The stone statue standing there today dates from 1904.

The roof table measures 5.75 m long, 3.55 m wide and 0.75 m thick. The orthostat on the north side measures 2 m high, 1.50 m wide and 0.20 m thick. It continues to the west with a dry stone wall which does not appear to be original. The orthostat on the west side is slightly domed. It measures 2.55 m wide by 2.305 m high with a thickness between 0.40 m at the base and 0.30 m at the top. The southern orthostat is backed by the slope. It measures 2.50 m wide, 2.40 m high and 0.35 m thick. The internal chamber measures 5 m long by 3 m wide with a height under the slab of 2 m

A very beautiful sandy beach with clear water. The surf is quite gentle here. There's a beautiful view of the Château de Costaérès.
