Granada's cathedral is huge, but you don't appreciate its size unless you see it from above because so many other buildings crowd around it. Make sure to look at it from the Alcazaba de la Alhambra (Alhambra fortress) or even further back, from the Abadía del Sacromonte (Sacromonte Abbey). It stands in the centre of town where the Great Mosque stood during the Moorish occupation. Alongside are the Capilla Real (Royal Chapel) and the Palacio de la Madraza (Arab University). Work began in 1521 when the adjoining Royal Chapel was completed.
