Commissioned after the Reconquista of the city, the Royal Chapel holds the tombs of King Ferdinand II and Queen Isabella I, the famed Catholic Monarchs who conquered the city and decided to be buried at the site of their victory. The chapel was constructed in Gothic style but the intricate marble tombs are done in Renaissance style. Additionally, Ferdinand and Isabella's heirs Juana I (Juana la Loca) and Philip I (Felipe el Hermoso) are buried here. Aside from the beautiful and intricate artwork in the chapel and high altar there is also a museum on-site with a number of objects symbolizing Ferdinand and Isabel's rule, including Isabella's art collection, crown and sceptre and Ferdinand's sword.
