The Torelló settlement was one of the largest in the municipal area of Mahón. It is especially well known for the spectacular talaiot (called the Talayot of Torellonet Vell) which is interesting because at the top of the tower you can still see the original doorway and the lintel above it, both of which date from the Talayotic period (1000-700 BCE).
Unfortunately, the structure was damaged by the triangulation pillar and the airport-runway approach lights that were placed on the tower platform. An archaeological dig carried out on the site in the 1980s unearthed lamps dating from the period of Imperial Rome plus the remains of fine Roman pottery.Of all the structures identified in the settlement, the most interesting are a second talayot (much smaller in size); the foundations of several houses; a couple of artificial caves; plus a water catchment system made up tanks or cisterns and channels.
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.
