A portico is a roofed passage that consists primarily of a series of giant and sharp arches that lead to the yard of a building.[1] Porticos are usually used in the construction of religious houses of worship like mosques and churches.
Al-Aqsa mosque has two main porticos: the western portico and the northern portico.[2] These porticos date back to the Ayyubid and Mamluk periods. The main reasons these porticos were built was to connect the landmarks of Al-Aqsa plaza and to protect people in the mosque in the event of severe weather.[3]
