Despite its age, the Cathedral, on which construction began in 1525, is one of the peninsula's most modern Gothic structures. Charles V commanded the construction of a new Cathedral separate from the Alcázar. Designed by the architect Juan Gil de Hontañón, the Cathedral is known as the Lady of the Cathedrals due to its elegant proportions and refined design. The architect passed away soon after work began, and he was superseded by his son Rodrigo. It ended up taking around two centuries of continuous labor to complete. The plot came from the confiscated houses in the Jewish quarter and from the Clarissa Nuns Monastery. In 1768, the Cathedral was consecrated to Our Lady of the Assumption and Saint Frutos.
