The Ancient Roman influence is visible in some of the architectural elements, including the building's columns and foundations.

[1] Similar Romanesque churches with triple apses were built in Tyre and Tartus, using recuperated material such as Roman columns and capitals.

[2] In 1291, in the Ottoman era, the Mamluks captured Beirut, and under Islamic conquest the church was again converted into a mosque.

Its Mamluk-style entrance and domes and minarets were added in 1350, reflecting traces of the former church's Byzantine style.

[1][3] Badly damaged during the Lebanese Civil War, the mosque's refurbishment was completed in 2004,[1] under the direction of Youssef Haidar.
