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 ancient Argos Theater was built in 320 BC. and is located in Argos, Greece against Larissa Hill. Nearby from this site is Agora, Roman Odeon, and the Baths of Argos. The theater is one of the largest architectural developments in Greece and was renovated in ca 120 AD.
The Hellenistic theater at Argos is cut into the hillside of the Larisa, with 90 steps up a steep incline, forming a narrow rectilinear cavea. Among the largest theaters in Greece, it held about 20,000 spectators and is divided by two landings into three horizontal sections. Staircases further divide the cavea into four cunei, corresponding to the tribes of Argos A high wall was erected to prevent unauthorized access into the theatron and may have helped the acoustics, but it is said the sound quality is still very good today.
Around 120 CE, both theaters were renovated in the Roman style.
