Sayyidah Zaynab Mosque (Arabic: مسجد السيدة زينب‎) is a mosque located in the city of Sayyidah Zaynab, in the southern suburbs of Damascus, Syria. According to Shia Muslim tradition, the mosque contains the grave of Zaynab, the daughter of ‘Alī and Fātimah and granddaughter of Muhammad. Sunni Muslim tradition places Zaynab's tomb in the mosque of the same name in Cairo, Egypt. The tomb became a center of Shia religious studies in Syria and a destination of mass pilgrimage by Shia Muslims from across the Muslim world, beginning in the 1980s. The zenith of visitation normally occurs in the summer.
