Βασιλική Αγίου Μάρκου, Heraklion Travel Guide

The Basilica of St. Mark, or Agios Markos, stands proudly on Eleftheriou Venizelou Square (also known as Lions Square) in the center of Heraklion. This historic building, constructed in 1239 during Venetian rule, has witnessed many transformations, reflecting the diverse cultural influences that have shaped Crete.Initially built as a Roman Catholic church, it served as the metropolitan Cathedral for four centuries, dedicated to the patron saint of Venice, Saint Mark. The basilica was used by the Duke and high-ranking officials of the local commune. Its architecture, featuring slender marble columns, high arches, and Venetian-inspired design, distinguished it from other churches on the island. The church even had tombs in its yard for members of the Duke's family. However, earthquakes caused severe damage to the Basilica in 1303 and 1508, but it was restored shortly after each time.In 1669, with the Ottoman conquest of Crete, the basilica was converted into a mosque known as Defterdar Ahmet Pasha Mosque. The bell tower was destroyed, frescoes were damaged, and tombs were desecrated. The minaret was torn down in 1924.Following the Greco-Turkish population exchange in 1924, the building eventually came under the administration of the Municipality of Heraklion. After undergoing restoration in 1956, it was transformed into a Municipal Art Gallery. Today, the Basilica of St. Mark hosts a variety of art exhibitions, theater shows, poetry recitals, musical concerts, and other cultural events, and is open to the public free of charge.
