The cave of Chufín is situated at the confluence of the Lamasón and Nansa rivers. Several caves are ornamented with rock art pock the steep slopes above the water. Chufín is one of the caves included in UNESCO’s list of World Heritage sites under the entry Cave of Altamira and Paleolithic Cave Art of Northern Spain.
In Chufín were found different levels of occupation, the oldest being around 20000 years old. The small cave has some subtle engravings and paintings of red deer, goats, and cattle, all represented very schematically.
Also found in the cave were many symbols. One group, called type 'sticks', accompanies the paintings inside animals. There are also many drawings using points (puntillaje), including one which has been interpreted as a representation of a vulva.
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.
