Chapel dating from the 16th century, restored in 1732 (according to inscription). The pinnacle dates from the year 1609 (bears the date). Sainte-Barbe was the chapel of the coastguard whose batteries defended the port of Toul an Héry against the English invader, from the end of the 16th century until the Napoleonic era. It even served as a barracks when, in year IV, it received the artillerymen of the 2nd battalion of the Hautes-Alpes. However, the chapel existed long before the creation of the coastal militias. After the Revolution, the chapel of Sainte-Barbe was regularly maintained by Jacob, former boss of the customs of Toul an Héry, whose two sons, Yves and Joseph, continued as heads of the factory, to preserve the building piously. It belonged, according to René Couffon, to the Morlaix hospital during the Revolution and was sold as national property, then given to the factory on December 7, 1823. The building has been listed on the additional inventory of Historic Monuments since October 9 1934.

Hogolo Baths

Highlight • Viewpoint

Located on the Corniche de l'Armorique in Plestin-les-Grèves, the remains of the Hogolo are a remarkable testimony to the Gallo-Roman presence in Brittany: A real living history book which allows you to follow the daily path of the Romans in their ablutions. In addition to its historical interest, the site offers a very beautiful view of the Bay of Locquirec, where the Douron completes its course.
The discovery on the site of a large dumping ground for food waste (shells, bones), agricultural and fishing tools showed that at the end of the 2nd century, the thermal building was transformed into a dwelling house occupied by people of more modest means. The building was destroyed at the end of the 3rd century or the beginning of the 4th century.
