Origin and history

The Church of the Trinity of Brélévenez, located in Lannion in the Côtes d'Armor, is an emblematic building of the transition between Roman art and Gothic art. Built from the end of the 12th century on 11th century substructures, it stands on the hill of Crec'h Tanet, accessible by a 140 steps staircase. Its history remains partly enigmatic, for lack of precise archives, but its architecture suggests a monacal origin, perhaps linked to Trinitarians, Templars, or the Order of Montjoie, as suggested by tombstones engraved with crosses of Malta and swords.

In the 13th century, two side chapels forming a false transe were added, while in the 14th century, the church was fortified by Olivier V de Clisson during the War of Succession of Brittany. John IV, Duke of Brittany, intervenes for his demilitarization, leading to the resumption of the walls of the nave and the vaults of the lower side. The bell tower, built in the 15th century, crowns the ensemble. The choir was redesigned in the 17th century to accommodate a baroque altarpiece commissioned by Count Pierre de Laval, and the church became parishioner in the 18th century, replacing that of the Rusquet.

Ranked a historical monument in 1909, the church combines heterogeneous materials: pink granite for Romanesque parts (such as the bedside adorned with committed column foothills) and green shale for later additions. Its interior is impressed by a nave of 11 spans, a walk-through with axial chapel, and baroque altarpieces, including an imposing altarpiece of 1660 in tuffeau and black marble. The crypt, rebuilt in 1809, houses an 18th century Polychrome Tomblay. After restorations in the 1990s, the church was closed in 2025 for security reasons.

The exterior is distinguished by its Romanesque south porch, its 15th-century bell tower-poach surmounted by an octagonal arrow, and the Tower Lead, a vestige of the fortifications of the 14th century. Inside, the vaults of the lower side, taken up at the end of the 14th century, bear the coats of arms of local families such as the Kérimel or the Trogoff. The furniture also includes 15th-century baptismal fonts, an 18th-century pulpit, and an 1862 organ buffet, restored in 1980.

The church illustrates the ambition of its anonymous sponsors, its defensive role during the Breton conflicts, and its evolution into a parish centre. Its Latin cross plan, its vaulted walkway (reserved for prestigious buildings), and its mix of styles make it a major witness to Breton religious heritage. Local tradition also evokes a link with the Templars, although this hypothesis remains debated in the absence of archival evidence.
