Agios Titos Church in Heraklion, Crete
This majestic church dominates the eponymous square. It has Byzantine origins in AD 961, was converted to a Catholic church by the Venetians and turned into a mosque by the Ottomans, who also rebuilt it after the devastating 1856 earthquake. Agios Titos in Heraklion has been an Orthodox church since 1925. Since 1966, it has once again sheltered the much-prized skull relic of St Titus, returned here after being spirited to Venice for safe-keeping during the Turkish occupation.
