The Monastery of San Juan de los Reyes was commissioned by the Catholic Monarchs in the city of Toledo (Spain) to honor the victory in Battle of Toro in 1476. This battle put the end to the War of Succession in favor of Princess Isabel, sister of the late King Enrique IV. They fought against the supporters of Juana, illegitimate daughter of the king. At first, the architecture and decoration were designed for the tombs of the monarchs, years before conquering Granada, where they were buried at the end.
The stone arches show the motto "Tanto Monta" which refers to Alexander the Great when he arrived at Gordio, where a yoke with a complicated knot symbolized the promise to conquer the East. Alexander cut the knot with his sword and exclaimed: "tanto monta", which means "there is no difference". This motto shows that the King and Queen ruled in equal terms in each of their kingdoms.
