The Church of Santa María de la Asunción is in Gothic style. Built under the protection of King Alfonso VIII of Castile in the 13th century (though it was finished in the 15th century), it is a basilica church with three naves. In the interior are the images of the White Virgin and the Reclining Christ, and three Gothic carvings of the Magi.
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.
