 When the building was transformed into a mosque from a cathedral, most of the previous Crusader construction was completely replaced, but the mosque's facade with its arched entrance is a typical piece of Crusader ecclesiastical architecture, and columns within the mosque compound still retain their Italian Gothic style. Some of the columns have been identified as elements of an ancient synagogue, reused as construction material in the Crusader era and still forming part of the mosque. Internally, the wall surfaces are plastered and painted. Marble is used for the western door and the dome's oculus. The floors are covered with glazed tiles. The columns are also marble and their capitals are built in Corinthian style.
