The walls are very lofty and not much injured by time; the plan of the various chambers, extensive vaults and chambers in the inner courtyard, can be perfectly distinguished. The general form of the castle, which must once have been very strong, is nearly a square, with a projecting gatehouse to the S.E. which is almost perfect. The keep on the eastern side commands a lovely view. About half a mile further is the village of Oystermouth, clustering with its whitewashed roofs along the foot and declivity of a high mass of rock, which juts boldly out into the sea for half a mile, forming the south-eastern extremity of Gower, and terminating Swansea Bay. The village is celebrated as a bathing place, and for its extensive fishery for oysters, with which it supplies Bristol, Gloucestershire, North Somerset, &c. This trade gives occupation to a considerable number of fishermen who are the chief inhabitants of the place; but in the spring and summer, Oystermouth, in consequence of the great beauty of the situation, and its extreme salubrity, is completely filled with strangers, and high rates are obtained for lodgings; the accommodations are mostly indifferent, though the place is improving fast. The prospect from the summit of the rocks is truly exhilarating and beautiful. On one side, the spectator beholds just below him, the Atlantic rushing with all its majesty up the Bristol Channel--rising over the mixon sands into a really mountainous swell--while on the other, Swansea Bay, glittering with the white sails and varied combinations of a crowd of shipping, seems spread out like a vast and beautiful lake; its eastern shores bounded in the distance by the mountainous and woody scenery of Britton-Ferry, Aberavon, Margam, gradually diminishing towards Pyle.
