Crowds gather at night in Cairo Opera House Square (Midan El-Opera) to watch Al-Leila El-Kebira (الليلة الكبيرة), a renowned Egyptian folk musical theater production by Sayed Hegab and Omar Khairat. The performance is staged from a vibrantly decorated mobile theater truck, featuring traditional Egyptian truck art (Fan El-Otobis) with colorful patterns and Arabic calligraphy. Al-Leila El-Kebira is one of Egypt's most iconic cultural productions, celebrating popular heritage, Sufi traditions, and Egyptian street culture.
