The Western Marble Arch (WMA) Synagogue is a Jewish place of worship in central London. The WMA is the result of a merger between the Western and the Marble Arch Synagogues, with the former congregation dating back to 1761. The current building is in Great Cumberland Place, Westminster. It is a leading Orthodox Judaism synagogue and offers religious and social activities to its members and the wider community.
The Western Synagogue was founded in 1761 in Great Pulteney Street, Westminster. The congregation, formally named, in the transliteration of the era, Hebra Kaddisha Shel Gemillith Hassadim, Westminster (Holy Congregation of Acts of Charity, Westminster) first met in the home of Wolf Liepman, a prosperous immigrant merchant from St. Petersburg. A series of leased spaces followed until 1826 when the congregation built an elaborate synagogue in St. Alban's Place, Haymarket (London) and renamed itself The Western Synagogue.
