The convent of Santa Clara in Zafra is the site of the museum of the same name, dedicated to the history of the city and to the nuns of the order of the Poor Clares who have inhabited it since its foundation.
The convent was founded in 1423 by the first Lord of Feria, Gómez Suárez de Figueroa, who is buried here in a Gothic alabaster tomb. The buildings and constructions on the site form a chronological arc ranging from the 15th through to the 18th century.The church has a rectangular floor plan, a nave with a barrel vault and a square sanctuary (17th century). There is a main chapel, a sacristy, the nuns' choir stalls, the funerary chapel of the Dukes of Feria and two porticoes, one in the classical style (17th century) and the other Mudéjar (16th century). Other elements of the site are the cloister, with pointed semicircular arches, and various other rooms.
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.
