The Jericho synagogue is a Jewish synagogue in Jericho, West Bank, Palestine. The synagogue was built in the Byzantine Empire-era and is believed to date from the late 6th or early 7th century CE and was discovered in 1936. All that remains from the ancient prayer house is its mosaic floor, which contains an Aramaic inscription presenting thanks to the synagogue donors, and a well-preserved central medallion with the inscription "Shalom al Israel", meaning "Peace [up]on Israel". This led to the site also being known as Shalom Al Israel Synagogue.
