Santiago del Arrabal was built in 1245-1248 at the orders of Sancho II on the site of an older church and a mosque that is known to have been used since 1125. Many characteristics of the mosque have remained in the present building which is built in the Mudéjar architectural style. The church is named after Saint James (Santiago) of the outskirts (Arrabal). The patrons of the church during its foundation were members of the Diosdado family, knight commanders of the Order of Santiago.
