Guests on the Free Essential Tour Granada will navigate the charming streets of the historical district. One of the highlights of the area is, of course, the majestic Cathedral. This stunning structure, like many other cathedrals in Andalusia, was built on top of the former city mosque. There guests will enjoy another important religious landmark: the Royal Chapel, the final resting place of the Catholic Kings, Queen Isabella I and King Fernando. Here guests will discover more about the fall of the Nasrid Dynasty and the reign of the Catholic Monarchs. The third monument that completes the set of essential religious buildings is the Basilica of San Juan de Dios, one of Granada’s more modern structures, built in the 18th century. It is an incredible example of baroque styling.
