As is the case of most Christian buildings in Granada, the Cathedral was built on the site of the former Mosque. The site of the former Mosque has since been replaced by four buildings: the Cathedral, the Royal Chapel, the Sagrario, and the Merchants' Exchange.
Granada Cathedral: 16th century - on site of former main mosque - Gran Vía
For me, the most striking fact about the cathedral is the incredibly long time it took to build. Work on the cathedral began on 15th March 1523 and it was not completed until 1704, 180 years later. Building stopped during the plague, and several architects were involved including Juan Gil de Hontañón, Enrique Egas, Diego de Siloe, etc.
There is a restaurant at the back of the cathedral called the Via Colón.
