There is a stone here, Postman, but I hope you won’t kick yourself for missing it.
Carreg y Llech.
A monolith of sandstone, containing nuggets of iron stone, some of which have dropped out, leaving holes or pockets. It stands in a low-lying meadow, and is 6 feet high, 6 1/2 feet broad, with an average thickness of 18 inches, and leans towards the west. The remains of a low bank or base of earth, 6 inches high, are perceptible to the west, and around the stone can be seen what appears to be a rough pavement of small cobbles. – Visited, 1st June, 1910.
This is from the Flintshire Inventory of Ancient Monuments (1911). It’s on Coflein too.
