Bevis Marks Synagogue, officially Qahal Kadosh Sha'ar ha-Shamayim, is the oldest synagogue in the United Kingdom in continuous use. It is located off Bevis Marks, Aldgate, in the City of London. The synagogue was built in 1701 and is affiliated to London's historic Spanish and Portuguese Jewish community.

The Bevis Marks Synagogue Heritage Foundation is an independent charity, created in 2019 by the Spanish and Portuguese Sephardi Community, to preserve and manage the buildings, archives and collections of the Bevis Marks Synagogue.

The Foundation’s vision is to enable Bevis Marks’ living community to thrive and develop the Synagogue into a vibrant meeting-place which welcomes visitors of all faiths and none to celebrate and learn about the history, culture and traditions of the Spanish and Portuguese Jewish community.
