The Hermitage of Sant Serni de Nagol is a historic chapel located in Andorra, specifically in the parish of Sant Julià de Lòria. This small Romanesque church dates back to the 11th century and is dedicated to Saint Saturninus (Sant Serni in Catalan). Perched on a hillside, the hermitage offers stunning views of the surrounding valley and mountains. Its simple yet charming architecture is characteristic of the Romanesque style, featuring a single nave, a semicircular apse, and a bell tower.
