The construction of this beautiful Roman church began in the medieval streets above the harbor in 1115 AD, and the structure was expanded and improved over the subsequent centuries, and today it has a striking architectural design, which is an interesting mixture of Arab and Western European designs, with remains of mosaics Byzantines are from previous buildings scattered around the area, and the huge cross sits at the top of the church in the open air, facing the northern wall, with the four arches and corners topped by a dome. You must definitely visit this beautiful church when you visit the Lebanese city of Byblos.
