Gwybodaeth am y darganfyddiad

Enw'r Safle: Ogof-yr-Ychen, Caldey Island

Nodiadau: Chamber 4 found lying on the surface - seemingly undisturbed since the chamber was sealed by the Roman layer - There were no signs of disturbance by burrowing animals as in Chamber 2 nor post-Roman blown sand layer either - extra proof of the chamber being sealed in Roman times.
