You may never have seen a more ancient church than the one you'll find in Crespià. Sant Miquel de la Roca is a “troglodyte” sanctuary. No, your eyes aren’t deceiving you! This sanctuary is partly built into a rock cavity on a cliff overlooking the Fluvià river. The views are just wonderful. It is also worth exploring this small town in Pla de l'Estany, with streets and lanes that still preserve the atmosphere of the ancient past.
