Cantre'r Gwaelod

Cantre'r Gwaelod is a legendary sunken kingdom said in Welsh tradition to have occupied a low-lying tract of land in what is now Cardigan Bay. The story describes a defended plain with a dyke (Sarn Badrig), sluice gates and a capital called Caer Wyddno; physical traces associated with the legend include ridged causeways (sarnau) and a submerged forest revealed at low tide. The site exists today as tidal sands, exposed tree stumps and offshore stone ridges.

As it stood in AD 500

What Cantre'r Gwaelod looked like in its prime.

A broad, very low coastal plain of intertidal sands and shallow tidal pools, ringed by a low earthen-and-stone dyke and a straight stone causeway (sarn) running into the sea. Small compact houses of local stone and wattle with steep thatch roofs cluster around a simple stone church with a square bell-tower. Wooden sluice-gates sit in narrow drainage channels; coppiced timber walkways and posts cross damp peat and reed margins. Colours: muted green marsh, brown thatch, grey stone and pale reflective pools.
