Ses Païsses is a Bronze Age talayotic settlement in northeastern Majorca. It is one of the most important and best-preserved prehistoric sites in the Balearic Islands, although it is largely overgrown with woodland, mainly Quercus ilex (holm oak), making it impossible to see the site as a whole.
The Ses Païsses settlement is thought to have begun as a cylindrical talaiot, or 'turriform', built during the first millennium BC (c. 900–800 BC) on a hillside with a commanding view of the surrounding countryside. Originally it would have stood alone, probably as a territorial marker. The tower is 12m in diameter and still stands 4m tall; there are stairs within the massively thick wall, but the building's central column has not survived. Visitors to the site are not allowed to access this building.
The talaiots are Bronze Age megalithic structures on the islands of Menorca and Majorca. There are at least 274 of them. Dating from the late second millennium and early first millennium BC (between 1,300–900 BC), they are round or square structures built of rough stone, around a central space at the center of which stood a column. This supported a ceiling of stone slabs which also formed the floor of the next story. Their purpose is not clearly understood: religious or tribal ceremonies, storehouses and distribution centres have been suggested. They are not thought to have been used as dwelling places or as defensive buildings.
These monuments pre-date the taulas, which are usually found nearby. The Talaiotic Culture began some 3,000 years ago and ended with the arrival of the Romans in the Balearic Islands in 123 BC.
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.
