1798 - Interesting Intelligence from Various Parts of the Country - Penarth Point - As published within The Gentleman's Magazine v.83. : -

Feb. 28. Some labourers, digging for limestone on the summit of a cliff near Penarth Point, in the county of Glamorgan, discovered the remains of four human bodies, lying about five feet beneath the surface of the earth ; two large stones were placed edge-ways, one on each side ; and a third on top, forming something like a coffin. How long they had lain there, no conjecture can be formed ; several teeth were perfect, but the bones mouldering into dust ; the appearance of four skulls certified that so many bodies were placed as it were one coffin. In the course of the two following days, the remains of three more bodies were found nearly on the same spot. By the direction of Thomas Bridges, Esq. of Kymmin cottage, the bones were all carefully collected, deposited in a wooden crate, and decently interred in the church-yard of Penarth. - Gentleman's Magazine v.83.
