Located about a miles walk from Zennor on Amalveor Downs is Zennor Quoit.
A large early Bronze Age burial chamber, with 7 upright stones and a humongous capstone weighing an estimated 12.5 tons.
The triangular profile is the result of the quoit's collapse - originally the capstone would have rested on top of the uprights.
It's current disposition dates back to 1861 when a local farmer decided to demolish the quit and build a cowshed. He was stopped by the local vicar but you can still see the stone posts that were to be the cow shed at the right of the photo
