The monastery had its origins in the late 13th century, when a shepherd from Cáceres, named Gil Cordero, discovered on the bank of the Guadalupe River a statue of the Blessed Virgin, which had been hidden by local inhabitants from Moorish invaders in 714. On the site of his discovery, a chapel was built, dedicated under the title of Our Lady of Guadalupe.
King Alfonso XI, who visited the chapel more than once, invoked Santa Maria de Guadalupe in the Battle of Rio Salado. After gaining the victory, he ascribed it to the Madonna’s intercession, declared the church at Guadalupe a royal sanctuary and undertook an extensive rebuilding program.
There are actually four buildings on the site now.
