 The Archbishop's Palace owes its name to that Alcalá de Henares for eight hundred years belonged to the jurisdiction of the archbishops of Toledo, who were also the primates -the most preeminents- of all Spain, and that here had their residence.This made that Alcalá de Henares was always at the center of religious power, which for centuries was also synonymous with the political.In the Archbishop's Palace also lived many members of the Court and was killed the Castilian King John I in 1390, after falling off his horse nearby.
