The small church of Oratorio di Santa Maria in Valle (also known as Lombard Temple), next to the Natisone river, is a notable example of High Middle Ages art sometimes attributed to the 8th century, but probably later. Included in the old Lombard quarter, it was probably used as Palatine Chapel by the Lombard dukes and king's functionaries. The fine decorations, statues and stuccoes (11th or 12th century) housed in the interior, show a strong Byzantine influence.

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.
