The Museum of Fine Arts of Seville has a collection of mainly Spanish visual arts from the medieval period to the early 20th century, including a choice selection of works by artists from the so-called Golden Age of Sevillian painting during the 17th century, such as Murillo, Zurbarán, Francisco de Herrera the younger, and Valdés Leal.
The building itself was built in 1594, but the museum was founded in 1839, after the desamortizacion or shuttering of religious monasteries and convents, collecting works from across the city and region. The building it is housed in was originally home to the convent of the Order of the Merced Calzada de la Asunción, founded by St. Peter Nolasco during the reign of King Ferdinand III of Castile. Extensive remodeling in the early 17th century was led by the architect Juan de Oviedo y de la Bandera.
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.
