The 우마이야드 모스크, also known as the Umayyad Mosque, is one of the largest and oldest mosques in the world, located in Damascus, Syria. It was built during the Umayyad Caliphate in the 8th century and is renowned for its stunning architecture, featuring intricate mosaics and a large courtyard. The mosque is considered a significant religious site for Muslims. Originally, the site was home to a Roman temple dedicated to Jupiter, which was later converted into a Christian basilica before the mosque was constructed.
