Santa María la Blanca is a historic synagogue located in Toledo, Spain. Built in the 12th century, it is one of the oldest synagogues in Europe and showcases the Mudéjar architectural style, which blends Islamic and Christian influences. The building features beautiful arches, intricate plasterwork, and a serene atmosphere, reflecting the rich cultural heritage of the Jewish community in medieval Spain. In 1492, following the Alhambra Decree, the synagogue was converted into a church, and it is now known as the Church of Santa María la Blanca. Despite its transformation, the original architectural elements remain, making it a significant site for both historical and religious studies.
