The Notre-Dame-de-Tronoën chapel near Saint-Jean-Trolimon is located not far from the bay of Audierne in southern Finistère. It was built in the 15th century and is also known as the "Cathedral of the Dunes" due to its location in the dune landscape. Originally it was dedicated to Saint Maudez, later to Notre-Dame de Tronoën, who was particularly invoked by families of missing sailors. The chapel is famous above all for its monumental Calvary, created between about 1450 and 1470. It is considered the oldest of the great Breton Calvaries. On three levels, numerous granite figures depict around 30 scenes from the life of Christ. Together, the chapel and the Calvary form one of the most important religious monuments in the Pays Bigouden.
