The Byzantine Ruins of the Church of John the Baptist (Qasr al-Yahud) are located near to the Jordan River. The church was located adjacent to a pilgrimage site where, according to tradition, Jesus was baptized by John the Baptist. This site is also traditionally identified as the site where the ancient Israelites first crossed into the "Promised Land" (Joshua 3) - hence the reason for the Arabic name of al-Yahud ("of the Jews").
