ANSEDONIA (Porto Santo Stefano). The city wall of Cosa was built at the time of the foundation of the colony on 273 BCE. Itis 1500m long and built in polygonal masonry of Lugli's third type. It included a system of interval towers, numbering eighteen in all. These are found at irregular intervals, and all but one are rectangular in plan - the exception is round. There are three gates which correspond to as many roads: the northwest, or Florentine gate, which corresponds to the modern entrance to the site, the northeast, or Roman gate, and the southeast, or maritime gate. These each have the same structure, twin gate, one in line with the walls and one to the inside, with a space between them. The arx also had an independent circuit wall.At the western corner of this was a postern, closed in the early Byzantine period, when the hill was refortified with a wall built with an emplecton. A final, medieval, circuit in mortared rubble masonry runs along the same line. In recent years the Archaeological Soprintendenza of Tuscany has conducted extensive documentation, repairs and reconstructions of the walls. #ansedonia #seaofansedonia #loveoflife💕 #carpediem #marcusberesford #enjoylife #liveandwork #livemoments #happyness😊 (presso Resti Della Città Di Cosa) https://www.instagram.com/p/CD3yRvnBwEc/?igshid=1gg6erquqjoxb
