The Sultan Hassan Mosque, built between 1356 and 1363, is one of Cairo’s most monumental examples of Islamic architecture. Located near the historic Citadel, this mosque-madrasa complex was commissioned by Sultan Hassan, a Mamluk ruler, and embodies the splendor of Mamluk design with grand arches, intricate stonework, and an expansive central courtyard. Famous for its massive size, symmetrical design, and towering 68-meter minaret, the mosque is an architectural marvel. Inside, it houses four iwans (vaulted halls) representing the four Sunni Islamic schools, reinforcing its significance as a center of both worship and learning in medieval Cairo. The mosque’s elaborate mihrab, soaring dome, and decorative details reflect the height of Mamluk innovation, making it a must-see for visitors interested in Islamic art and history.
