The Rafal Rubí navetas are two tombs of the same type as the Naveta des Tudons, but these are smaller and are unusual in that they are very close to one another. They are group burials with a perforated stone slab at the entrance to the inner chamber, which is split into two levels.
Of the two navetas, the east one is in better condition, as the front was restored in the late 1960s, when an archaeological dig was also carried out during which burial goods were found, including pottery items, rhomboid-shaped bronze pendants and part of a torc. The west naveta was excavated in 1977 and the human remains found in the upper chamber were dated to 904 B.C.The items found are on display in the Museum of Menorca.
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.
