Situated between the Ménez Bré and Ménez Houguéné, Louargat is a commune that spreads over 5723 hectares which makes it the 6th of the departement.

The commune is situated on the edge of the Coat an Hay forest which has many historical sites worth seeing : the Pergat menhir (one of the tallest in Europe), the Saint Michel Gaulish stele which dates back to the iron age, the pierced Crec’h Even stele, various Roman remnants, two churches and their fountains (Louargat’s and Saint Eloi’s), five chapels (Christ, Saint John, Saint Paul, Saint Sylvestre and Sainte Marguerite), the Cleuziou and Largez Manor Houses (the latter having belonged to Raoul, William the Conqueror’s brother in arms during the conquest of England in 1066).

The Méné Hoguéné (304m) offers a panorama over the whole region : Louargat, the Ménez Bré, the trégor coast, the Coat an Noz and Coat an Hay forests.
The Méné Hoguéné used to be a place where justice was handed out under the authority of the lords of Coat Quiziou and Guermorvan.
The guilty were hanged on top of Hoguéné’s highest point – a bank separated them from the spectators.

The Méné Bré (302m high on top of which is the Chapel Saint Hervé) was where the fairs took place, founded by the abbés of Bégard, the powerful abbey of the neighbourhood. These fairs took place up until around 1960.
