Lessoc is a charming medieval village with an extraordinary architectural heritage. First of all, the fountain in the central square which is covered with an extraordinary bulb placed on stone piles. Dating from 1796, it is the last such example. Another attraction, but less known, is a 17th century church, restored in 1993-1994, which is full of works of art. Finally, the chapel of Notre-Dame-des-Neiges au Buth (1684) and an old covered wooden bridge over the Sarine (1667).
