 The synagogue was founded by Samuel ha-Levi Abulafia, Treasurer to Peter of Castile, in about 1356.The founder was a member of a family who had served the Castilian kings for several generations and included kabbalists and Torah scholars such as Meir and Todros Abulafia, and another Todros Abulafia who was one of the last poets to write in the Arab-influenced style favored by Jewish poets in twelfth- and thirteenth-century Spain.The synagogue was connected to Samuel ha-Levi Abulafia's house by a private gate and he intended to use it as a private house of worship.
