La leyenda de San Virila Curiosity · Yesa, Sangüesa, Navarra Image of Yesa, not of the place itself. According to legend, Abbot Virila of Leyre, documented at the monastery in 928, became so absorbed listening to a nightingale's song by a nearby spring that three centuries passed; he thus came to understand eternity when he returned and did not recognize a single monk. The spring, about a 30-minute walk from the monastery, can be visited today. 928 Photo: Basotxerri (CC BY-SA 4.0) What to see and do in Yesa
