The Great Mosque of Aleppo (Arabic: جامع حلب الكبير‎ Jāmi‘ Halab al-Kabīr) or the Umayyad Mosque of Aleppo (جامع بني أمية بحلب Jāmi‘ Bani Umayah Bi-Halab) is the largest and one of the oldest mosques in the city of Aleppo, Syria. It is located in al-Jalloum district of the Ancient City of Aleppo, a World Heritage Site, near the entrance to al-Madina Souq. The mosque is purportedly home to the remains of Zechariah, the father of John the Baptist. It was built in the beginning of the 8th century. However, the current building dates back to the 11th through 14th centuries.
