Discover Trégrom: viaduct, chapel and hiking trails

Trégrom offers several specific reasons to visit: the three-arched Viaduc de Trégrom, the Chapelle de Christ, the menhirs of Keranscot and hiking trails with varying route details. When planning, both route length and route type matter, as do the access conditions at individual attractions. You can organise your stay around architectural history, archaeological sites and hiking.

The viaduct and the trails

The Viaduc de Trégrom was built between 1860 and 1863 as a three-arched bridge. The footpath across the viaduct is 120 m long. The passage beneath the third arch is intended for walkers and provides a route to and from the former Moulin du Vicomte. This gives you two different points of reference for planning: a short crossing and the path to the former mill. Check the conditions for using the passage on site.

The An Dro Berr route starts at the parish enclosure. This easy walk is 1.3 km long and takes about 25 minutes. The Circuit du Viaduc starts in Trégrom and forms a 5.1 km circular route. Its green and yellow waymarks pass the Lavoir St-Brandan and then descend to the bathing area. When choosing between the two walks, it is worth comparing their length and layout: An Dro Berr is the shorter walk, with an approximate duration, while the Circuit is a longer loop with waymarks and named points along the route. The car park at the bathing area provides access to the GR 34A.

Chapelle de Christ and event date

The Chapelle de Christ dates from the first half of the 16th century and has been listed as a Monument historique since 2015. It houses a polychrome wooden gallery dating from the 17th to the early 18th century. The gallery was assembled from carved panels from a former rood screen. The dates distinguish the later gallery from the older chapel; its carved panels also point to a former rood screen. “Polychrome” means multicoloured and describes the decoration of the wooden gallery.

Events celebrating traditional crafts and occupations are held every year in mid-August in the placître of the Chapelle de Christ. If you would like to plan a trip around this event, check the specific dates in advance. This lets you plan your visit around the recurring time of year and factor the exact dates into your plans.

Menhirs and visiting conditions

The menhirs of Keranscot consist of two granite menhirs, measuring 6.20 m and 3.5 m tall respectively. They are on private land but are visible from the public road. If you would like to see the stones, plan to view them from the road and respect the private property. The two measurements make the difference in height within the group easy to compare.

The Church of Saint-Brandan is open only by prior arrangement with the mairie. Arrange your visit with the mairie in advance and check the current visiting arrangements. Unlike the menhirs, which are visible from the public road, visiting the church expressly requires a prior request.
