L’Écot was at one time, like Bonneval, a hamlet of Bessans. In the heart of L´Écot is the Romanesque chapel of Sainte-Marguerite, dating back to the 12th century. Although the hamlet is no longer inhabited permanently today, it was until about 1960. A number of houses have been restored in keeping with this exceptional building heritage. With wood being rare at this altitude, the local stone is used from wall to roof.
