Valmayor was an ancient village in Valdemorillo that, it seems, once had a significant population and was depopulated following the plague of 1600. In 1648 the village was declared depopulated and its church became a hermitage. Legend has it that the Virgin of Hope appeared to some shepherds and asked them to build a chapel in her honour on this site, and in this way the old parish church, now converted into the Hermitage of Valmayor, was created.
