The Umayyad Mosque (Arabic: ٱلْجَامِع ٱلْأُمَوِي, romanized: al-Jāmiʿ al-Umawī), also known as the Great Mosque of Damascus (Arabic: جَامِع بَنِي أُمَيَّة ٱلْكَبِيْر, romanized: Jāmiʿ Banī Umayyah al-Kabīr), located in the old city of Damascus, the capital of Syria, is one of the largest and oldest mosques in the world. Its religious importance stems from the eschatological reports concerning the mosque and historic events associated with it. Christian and Muslim tradition alike consider it the burial place of John the Baptist's head, a tradition originating in the 6th century. Two shrines inside the premises commemorate the Islamic prophet Muhammad's grandson Husayn ibn Ali, whose martyrdom is frequently compared to that of John the Baptist. It is considered to be the oldest mosque still in use in its original form. The site has been used as a house of worship since the Iron Age, when the Arameans built on it a temple dedicated to their god of rain, Hadad. It was later associated with the Greek god Zeus during the Hellenistic period.
