A beautiful Romanesque church, Eglise Saint Jean Marc is the cathedral church of Jbail-Byblos. The Church is dedicated to Saint Jean Mark, the patron saint of the town, who is said to have founded the first Christian community of Byblos. The church itself was built in 1115 A.D by the Crusaders, originally as the Cathedral of Saint John the Baptist. After their departure, earthquakes, invasions and other disasters have repeatedly damaged the structure, and for a few centuries it remained disused. In 1764, Emir Youssef Chehab, of the Druze dynasty that ruled a semi- autonomous Lebanon under the Ottomans, donated the church to L’Ordre Libanais Maronite (Lebanese Maronite Order) which subsequently restored and reopened in 1776 after re-dedicating it to St Jean Marc. British bombardments of Lebanon in 1840 caused further damage, but the church was restored yet again. Eglise Saint Jean Marc continues to serve the Maronite Christian community. One interesting feature in the church is its open- air domed baptistery on the northern side which dates from the original construction in 1115 A.D, The church is situated on Rue de Port, between the port and the archaeological area.
