Two worshippers walk through the grand arched entrance of Al-Hakim Bi-Amr Allah Mosque in Islamic Cairo, framed by ornate Fatimid-style arches adorned with green curtains and a decorative geometric frieze. Al-Hakim Bi-Amr Allah Mosque, built between 990 and 1013 CE during the Fatimid Caliphate, is one of Cairo's oldest and most historically significant mosques, located along Al-Muizz Street. The marble courtyard floor and cream-toned facade reflect the mosque's extensive restoration, making it an active place of worship and a major Islamic heritage landmark.
