On 11 August 1480, Ottoman forces breached the doors of this church, slaughtering the clergy and civilians who had taken shelter inside just three days before the mass execution of eight hundred citizens on the nearby Colle della Minerva. Today, Otranto Cathedral (Basilica Cattedrale di Santa Maria Annunziata), elevated to a minor basilica in 1945 by Pope Pius XII, stands as a monument to that siege. Founded in 1068 by the Norman bishop William over the remains of a Messapic village, a Roman house, and an early Christian temple, it was consecrated on 1 August 1088 by the papal legate Roffredo under Pope Urban II. The building is a synthesis of Byzantine, early Christian, and Romanesque architecture, heavily rebuilt after its temporary conversion into a mosque.
What to see
The hut-shaped facade bears the marks of the reconstruction ordered by Alfonso V of Aragon (Duke of Calabria) after he retook the city in 1481, notably the large 16-ray Gothic-Arabic rose window. The main Baroque portal, added in 1674, features half-fluted columns and a pediment displaying the coat of arms of Archbishop Gabriel Adarzo de Santander supported by two angels. A minor portal on the left side dates to the late 15th or early 16th century, built by Nicholas Fernando with a carved figure of its patron, Archbishop Serafino da Squillace. Measuring 54 metres long by 25 metres wide, the interior is divided into a nave and two aisles by twelve arches resting on fourteen granite columns with unmatched capitals (the entire structure is supported by 42 monolithic marble and granite columns from unknown quarries). The presbytery houses the high altar, adorned with an 18th-century silver antependium depicting the Annunciation. Above it, the triumphal arch and the black, white, and gold wooden coffered ceiling were commissioned by Archbishop Francesco Maria De Aste in 1693 and 1698. The aisles, capped by an 1827 painted plank ceiling by Archbishop Andrea Mansi, contain six altars dedicated to the Resurrection, St. Dominic, and the Assumption (right), and Pentecost, the Visitation, and St. Anthony of Padua (left). The left aisle also holds Archbishop Michele Orsi's mid-18th-century Baroque baptistery, the tomb of Francesco Maria de Aste (died 1719), and the mausoleum of Gaetano Cosso (died 1655). The right aisle culminates in the Chapel of the Martyrs, rebuilt at public expense in 1711 based on the original orders of Ferdinand I of Naples. Here, seven large glassed recesses hold the bones of the eight hundred citizens beheaded for refusing to abandon their Christian faith. Behind the marble altar lies the alleged "Martyrdom Rock" used for the executions, while small cupboards near the entrance contain organic remains preserved without special treatments. The entire floor is covered by a monumental mosaic (1163-1165) commissioned by Archbishop Jonatas and executed by Pantaleon, a Basilian monk from the monastery of San Nicola di Casole. Centred around the Tree of Life, it depicts Old Testament scenes, medieval bestiaries, and the Alexander Romance, including Alexander the Great flying to heaven harnessed to two griffins, an allegory of pride. Below the apse lies the 11th-century crypt, inspired by the Mosque of Cordoba or Theodosius' cistern, featuring three semi-circular apses and forty-eight bays supported by over seventy ancient and medieval columns. Outside stands the 12th-century square bell tower, built in carparo stone and white limestone, originally the base of a taller watchtower. The church also retains two organs: a 1960 Ruffatti instrument in the left transept, and the historic Kircher organ (1722-1752) in the right transept, featuring a carved wooden case, a 47-note keyboard, and a 9-note pedalboard.
Visiting
Exploring the interior allows you to trace the entire narrative of the 12th-century floor mosaic along the nave. Visitors have full access to the Chapel of the Martyrs to see the relics and the execution stone, and can descend into the 11th-century crypt to examine its forest of recycled ancient columns and surviving frescoes dating from the Middle Ages to the 16th century.
Our editors' tip
While in the left aisle, look for the Byzantine-style fresco of the Madonna and Child. It is one of the very few 13th-century paintings to survive the 1480 Turkish occupation. When the Ottomans converted the cathedral into a mosque, they destroyed the other frescoes but spared this one, as Mary is a recognized and respected figure in Islam.
