The rear of the tomb, showing, from the top, the chamber roofstone, a padstone resting in the (deliberately carved) shoulder of the eastern, rear sidestone and the backstone that leans inwards and would probably collapse if it wasn’t being held up by the western rear sidestone. The massive rear roofstone leans on the top of the back of the second roofstone, visible here just off centre.
