Afonso IV of Portugal
The sanctuary of Nossa Senhora da Assunção da Boa Nova, apart from its religious importance, is of national importance. In 1340, the Moors had invaded from Andaluzia, resulting in an alliance between Alfonso XI of Castile and his father-in-law, Afonso IV of Portugal, that culminated in the Battle of Río Salado. In honor of their assistance during the Marinid invasion, Maria of Portugal, Queen of Castile ordered the construction of the Gothic church to commemorate their victory.
