The Sha'ar Hashamayim Synagogue (Gate of Heaven) is located in Cairo, Egypt. The synagogue was also known as Temple Ismailia and the Adly Street Synagogue.
Its long time leader was Chief Rabbi Chaim Nahum. In 2008, the synagogue marked its 100th anniversary. The synagogue was built in a style evoking ancient Egyptian temples, and was once the largest building on the boulevard.
When the synagogue opened in 1899, there was a vibrant Jewish community in Cairo. The last time the synagogue was full was in the 1960s. Today the community numbers 30-40 members, most of them older women.
