Saint-Samson Chapel and Menhir

Highlight • Monument

The Chapel of Saint Samson was built in two phases, between 1575 and 1631.

It is the main element of a complex, combining the manor house (to the south), which was once accessed, the fountain (to the northwest), the entrance gate (to the northeast), and the Christianized menhir (moved to the foot of the porch).

The first phase, completed in 1575 (a date previously visible on a buttress of the gable), concerns the chapel itself (without the tower), a small Flamboyant Gothic building with a superb ornate door to the south (then the only access point to the interior of the building) and an apse intended to later house a painted stained-glass window. This foundation is believed to have been initiated by the lord who owned the Barac'h-Keruzec fief, who endowed this isolated territory with a Christian building, providing a rhythm for the peasants' lives.

A second phase, completed in 1610 (date visible on a window), concerns the construction of a western massif, with an entrance porch and a bell tower composed of a square tower flanked by a spiral staircase turret, surmounted by a dome. This achievement is inspired by the Beaumanoir style, developed during the previous century in the lower Trégor, from Morlaix to Lannion, very appreciated for its elegance and characterized in particular by a slender bell tower-wall.

Chapel of Saint-Uzec

Highlight • Religious Site

The chapel of Saint Uzec was erected in the 14th century, on the boundary of parishes between Pleumeur-Bodou and Trébeurden: the old path, with an east/west axis, still exists, and the Calvary would be the exact boundary between the two parishes. Located on an imposing rock, subsequently largely carved out to provide passage for the road, it faces the menhir of Saint Uzec, visible on the opposite side of the valley. It is adjoined, as is often the case, by a fountain recalling old rites of water worship. It was partially destroyed by lightning in 1974, and gradually restored thereafter, at the initiative of the residents of the neighborhood and the municipality.

Saint-Uzec Menhir

Highlight • Historical Site

The Saint-Uzec menhir (in Breton: Kalvar Sant-Uzeg) is a menhir located in the town of Pleumeur-Bodou, near the Saint-Uzec chapel towards Ile-Grande. The menhir was Christianized in 1674 during a mission of the "apostle of Brittany", the Jesuit father Julien Maunoir who had it inserted in a plasterwork with access by stile, had it painted, sculpted and surmounted by a cross. The Christianization of the “standing stones” testifies to a desire to assimilate previous religious signs. It shows the Church's desire to integrate the pagan worship of stones into religious syncretism.

Kerguntuil Megaliths

Highlight • Historical Site

A large, a really large stone slab as a cover – I was really astonished.
Here is the translation of the information panel:
The stone monuments of Kerguntuil are remains from the late Neolithic period (around 2000 BC). The passage grave, consisting of several stone slabs, and the dolmen are two very fine examples of megaliths (assemblies of large stones) erected in Western Europe during this period.
Did you know that these passages were rediscovered in the 1930s thanks to the dedication of local volunteers who excavated and restored the monument? It is very likely that our ancestors used these monuments as collective burial sites. Today, these remains bear witness to the architectural genius of these prehistoric people, but also to their worldview. Look at the engravings inside, on the pillars of the mound foundation burial: These pairs of raised protrusions, engraved in relief, are said to represent breasts and the Great Mother Goddess of the Neolithic period.
