The Synagogue of El Transito is famous for its rich stucco decoration, which bears comparison with the Alcazar of Seville and the Alhambra palaces in Granada. It was founded as a synagogue by Samuel ha-Levi Abulafia, Treasurer to Peter of Castile, in about 1356. The founder was a member of a family that 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.
King Peter probably gave his assent to the building of the synagogue to compensate the Jews of Toledo for destruction that had occurred in 1348, during anti-Jewish riots that accompanied the arrival of the Black Death in Toledo. The founder eventually fell foul of the king and was executed in 1360. The synagogue was converted to a church after the expulsion of the Jews from Spain. The building, which is in a good state of conservation for its age, is currently a museum.
After the expulsion of the city's Jews under the Alhambra decree in 1492, the Synagogue came under the Order of Calatrava, who converted the building into a church serving a priory dedicated to Saint Benedict.
References:The Walls of Constantinople are a series of defensive stone walls that have surrounded and protected the city of Constantinople (today Istanbul) since its founding as the new capital of the Roman Empire by Constantine the Great. With numerous additions and modifications during their history, they were the last great fortification system of antiquity, and one of the most complex and elaborate systems ever built. They were also the largest and strongest fortification in both the ancient and medieval world.
Initially built by Constantine the Great, the walls surrounded the new city on all sides, protecting it against attack from both sea and land. As the city grew, the famous double line of the Theodosian Walls was built in the 5th century. Although the other sections of the walls were less elaborate, they were, when well-manned, almost impregnable for any medieval besieger.
