Notre-Dame Chapel

Highlight • Religious Site

Built on the slope on the northwest side of a hill which has been a fortified point since the 10th century (in the 11th century the cartulary of the Benedictine abbey of Landévennec refers to this place by the name "Montagne de Nin near the bank of the river Hamn" ) the Notre-Dame chapel dominates the course of the canalized Aulne from a height of 35 m Its oldest parts date back to the beginning of the 13th century.
At that time it was the parish church of a small village built on a nearby hill, from which the place called "Le Vieux-Bourg" survives. The structure of the chapel will evolve over the next 5 centuries according to the different styles of the moment. But despite all these changes, a certain unity emerges that makes this church a small masterpiece of Breton architecture.

Beautiful idyllic town on the river L'Aulne. Ideal as an excursion destination to a café or just to roll through.

Châteaulin

Highlight • Settlement

Châteaulin is a "bridge town", that is to say that it owes its economic activity and its creation to the last bridge which was located over the Aulne. It is also a strategic city between sea and mountains. It is located near the estuary and the harbor of Brest and also close to the Armorican massif, and also along the Nantes-Brest canal.
Finally, it is a very good place to take a break.

Eglise Saint-Idunet Châteaulin

The church was completely rebuilt in 1869 in the neo-Gothic style on the site of the former priory church. The only visible vestige of the priory is a statue embedded in the wall of the presbytery car park with the inscription: M. Lolasulien Prieur: Chalin 1589.

Nice monument of local cycling. The climb from Châteaulin is short but very solid, a bit spicy in the cold! Still, the view is impressive, almost as much as the neighboring Menez Hom.
