Isabelle the Catholic was the first great queen of Europe, and her wedding to Ferdinand of Aragon would lead to the union of the two most powerful crowns of the peninsula. The legacy of her reign in the form of heritage is the protagonist of this program. Like the Palace where she was born in Madrigal de las Altas Torres, in Ávila. Or the Monasteries of Guadalupe and San Juan de los Reyes, where she displayed her deep religiosity. And of course, the Cathedral of Granada and its Royal Chapel, where the remains of this ambitious and timely queen rest.
