The Mosque of Sultan Al-Zahir Baybars is a square-shaped building that is surrounded by a stone wall. The top of the stone wall is decorated by a row of cresting.
Four towers fortify the exterior corners of the mosque. The mosque has three monumental projecting entrances.
The main entrance is at the western wall. It leads to a passage with a dome ceiling at the beginning and with a shallow dome at the end.
In the interior of the mosque there is a quasi-square court surrounded by aisles on all four sides. The most distinguished feature of this mosque is the chamber that precedes the mihrab, or niche indicating the direction of Mecca. It has a quasi-square structure, which occupies nine tiles and is covered with a red brick dome.
The south aisle consists of six colonnades. The eastern and the western aisles consist of three colonnades each. The northern aisle contains two colonnades and all its arches are supported by marble columns.
