The Morcenx area, bordered by the Bez and its tributaries, seems to have been occupied since prehistoric times. Flint tools, domestic furniture, and a cinerary (cremation ashes) box from the 1st Iron Age have been found there.
The church « sanctus Petrus de Morcencz » was mentioned in the Liber rubeus during the 12th century.
