The Ben Ezra Synagogue, sometimes referred to as the El-Geniza Synagogue or the Synagogue of the Palestinians, is situated in Old Cairo, Egypt. According to local tradition, it is located on the site where baby Moses was found. The land for the synagogue was purchased in 882 CE for 20,000 dinars by Abraham ibn Ezra of Jerusalem.
This was the synagogue whose geniza or store room was found in the 19th century to contain a treasure of abandoned Hebrew secular and sacred manuscripts. The collection, known as the Cairo Geniza, was brought to Cambridge, England at the instigation of Solomon Schechter and is now divided between several academic libraries.
