Monasterio de San Mill &n de Yuso Monastery #UNESCO WH 1053, King Garcia IV of Navarra intends to move the remains of Saint Milan to Najira. Legend has it that cattle pulling carts kneel because they can't bear the burden - traditionally, this is interpreted as saints wanting to stay where they are - so the king built a new monastery here, Yuso. It is also the birthplace of modern Spanish.
