Santa María de Bujedo Monastery was probably founded between 1159-1172. The oldest documentary evidence confirming the existence of the monastery dates from 1182. It was confiscated in 1835.
The church, built in the first half of the 13th century, has a Latin cross plan with a single nave. There are some remains left of the original monastery buildings dating to the the 13th century. Seven double capitals and four bases are preserved from the medieval cloister.
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.
