Towering over the surrounding blocks is this spectacular 16th century structure, the second-largest cathedral in Spain and noted for its bright Renaissance interior. Constructed after the Reconquista of Granada to replace the mosque on the site, the cathedral was laid out with Gothic foundations but built in the Renaissance style and decorated with Baroque elements. Upon entering you'll be behind the main altar, located beneath the towering circular Capilla Mayor (sanctuary) with its magnificent domed ceiling. Surrounding the sanctuary and the pews are a series of chapels with magnificent artwork, and the sacristy (tucked away on your right immediately after entering) holds a collection of fine paintings, mirrors, and furnishings. Additionally, the spectacular façade of the cathedral (on the west side of the structure, opposite the Gran Via) is worth walking around outside to view - based on the design of a triumphal arch, it overshadows the small square below.
