This fascinating and beautiful subterranean church was conceived by a Benedictine monk, Emilian, after which the village was named. Legend has it that Emilian and his successors took over 300 years to construct the vast network of underground passages, where Emilian was laid to rest. Highlights include the paintings in the Chapelle de la Trinite and the catacombs. Before you leave, you must climb the 196 steps to the top of the Church’s Bell tower for unparalleled views of this charming medieval village.
