- Sarn Badrig
Sarn Badrig, also spelled "Sarn Padrig" (Welsh for "
St. Patrick 's Causeway"), is one of several more or less parallel shingle reefs extending under the sea inCardigan Bay on the west coast ofWales . The causeway is made of glacial deposits left by receding ice sheets at the end of the lastice age .Sarn Badrig is the longest and most northerly of these, and extends south-westwards under the sea from Mochras Point, on Shell Island, near
Harlech , parallel to theLlŷn Peninsula for a length of about 20km, and can be seen at low tide. It is a hazard to shipping.A neighbouring causeway is that of
Sarn y Bwlch , which is close toTywyn .In Welsh legend it is one of the dykes which protected the drowned realm of
Cantre'r Gwaelod .External links
