Once thought to sit on top of buried treasure (a myth that has been disproved), Lanyon Quoit was actually designed as an ancient burial chamber or mausoleum. The stones were first erected in the Neolithic period (3500-2500BC), although their formation would have been slightly different – in 1815, they collapsed and were later repositioned lower to the ground, with a broken stone missing.
At the Madron/Heamoor roundabout, take the B3312 for Madron and stay on it until you see the quoit on your right. There is no designated parking, so you’ll need to find a pulling-in point along the road.
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.
