The Gothic design of San Juan de los Reyes Monastery was drawn by Juan Guas in 1477 and finished in 1504. The church was dedicated to Saint John the Evangelist and commissioned by Queen Isabella I of Castile and her husband King Ferdinand II of Aragon. They are referred to as the Catholic Monarchs. After they married in 1469 and won the Battle of Toro against Portugal, these events triggered Spain’s unification. Look closely between the statues of saints and you will see chains. These are from Christians who were imprisoned by the Moors. After an extensive renovation, the Monastery of Saint John of the Kings was returned to the Francian friars in 1954.
