The map of Cors Fochno compiled by T Lewis in 1790 shows the placename 'Warren Point' immediately behind the shingle ridge at the back of the beach. Further references to the rabbit warren are found in Sales Particulars dating to 1866, when it is described as 'one of the best rabbit warrens in the pincipality extending over nearly 100 acres; and an abundance of partidge, snipe and wildfowl'. At that time, the warren was associated with Ty Canol farmstead. The warren is again mentioned in association with Ty Gwyn farm in 1887 when the 'warren and pasture' is divided in to 5 parcels (70 acres, 11 acres, 28 acres, 61 acres, 52 acres). In 1910, the shooting rights over all of the Ynyslas Estate, including the warren, were let to a Mr Williams for £110 per annum.
