Monastery of San Salvador de Villanueva was founded in the 10th century by Count Santo (Osorio Gutiérrez). This Benedictine monastery today houses the Museum of Religious Art. The whole complex has been declared a Property of Cultural Interest, and consists of an abbey and the church, as well as various chapels, a monastery, two cloisters and a courtyard. The church’s Baroque façade is particularly worth noting. It was renovated in 1732 by Casas y Novoa, the master architect behind the cathedral in Santiago de Compostela.
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.
