The term "basilica," used above by Vincent Reboul, can have two different meanings for places of worship: + First, as an architectural style: In the Roman Empire, basilicas were secular buildings (market halls or courtrooms); the early Christian era partially adopted this architectural style and, for this purpose, also the term "basilica." + Second, "basilica minor" is an honorary title for special places of worship throughout the world (regardless of the aforementioned architectural style), which has been personally awarded by the Pope since the 18th century.

This beautiful water town, famous for its Château des Rohans, is located in Argoat. That is to say in the very center of the Breton peninsula. It is a city which has preserved the Napoleonic memory of the great works carried out during the reign of the emperor. The Blavet is experiencing spectacular floods here which have left their mark on the inhabitants. The most recent ones date from January 1995 and February 2014.

In addition to the Quelven chapel located in the town, the village of Guern has two other strong points: the very beautiful manor of Menorval and the proximity to the Sarre river. This very pretty watercourse tributary to the Blavet is still well preserved.

This chapel is so imposing in its dimensions and importance that it is known here as the Basilica. It is a marvel of 15th century architecture which features numerous gargoyles and a 70 meter high bell tower. All in pure Breton granite.
