"About half-way over the sand, the mouldering castle, with its extensive shattered walls and ruinated towers, makes a solemn, majestic appearance. Having arrived on the island, which is destitute of tree or shrub, except a few blasted thorns and briers, we left our horses at a lonely public-house, situated close by the side of the eastern shore, and proceeded to inspect the ruins of the castle. The main tower has been defended by two moats, two walls, and several small towers. We crossed the exterior fosse or ditch, and entered the outer bayle or yard, through a ruinous guard-tower, overleaning a steep precipice formed by the surges of the sea. The ancient pass, where the drawbridge over the outer ditch was fixed, has been long washed away. The greater part of the outer wall is also demolished, for in those places which are out of the reach of the tide the stones have been removed for various purposes.

"The drawbridge over the exterior ditch of these castles used commonly to be defended by a fortification consisting of a strong high wall with turrets, called the barbacan or antemural; the great gate or entrance into the outer bayle or yard was often fortified by a tower on each side, and by a room over the intermediate passage; and the thick folding-doors of oak, by which the entrance was closed, were often strengthened with iron, and faced by an iron portcullis or grate, sliding down a groove from the higher part of the building.

"A chapel commonly stood in the outer bayle: accordingly, just at our entrance into that part we saw the ruins of a building which is said to have been the chapel belonging to this castle.

"At the inside of the yard we came to the inner fosse, moat, or ditch, and arriving at the place where the drawbridge had been fixed, we entered the inner bayle or court by the ancient passage through the interior wall, the entrance whereof had evidently been secured by a portcullis, and defended by a room over the passage.

"We now proceeded to the entrance into the main tower or keep; but the doorway into the porch, which precedes it, being walled up, we were obliged to creep into the edifice by a narrow aperture. The entrance has been secured by a portcullis. The main tower has consisted of three storeys, each divided into three oblong apartments by two interior side walls being carried from bottom to top.

"The rooms on the ground-floor have been very low, and lighted by long apertures, extremely narrow, at the outside of the walls, but a considerable width in the inside, perhaps so constructed for the use of the bow. The apartments have communicated with each other; and there has been a winding staircase leading from one of them to the rooms above, and to the top of the castle. Under the ground-floor of these ancient castles used commonly to be dark and dismal apartments, or dungeons, for the reception of prisoners, but nothing of the kind is known to be here. The porch is called the dungeon.

"The second floor has been on a level with the first landing at the principal entrance. The rooms have been lofty, and lighted by small pointed windows, and many of them have had fireplaces. The apartments on the third floor have been apparently similar to those on the second. The side apartments have been lighted by several small pointed windows, but those in the middle have been very dark and gloomy.

"The great door of the castle opens into one of these intermediate apartments. On the left-hand side of the entrance has been a spiral staircase, leading to the rooms above and to the top of the castle, which has had a flat roof, surrounded by a parapet and several turrets. The walls of this tower are very strong and firm; a deep buttress is placed at each corner, and one against the middle of each side wall. A small square tower has stood at the southern corner, but the greater part of it has been thrown down by the sea. The foundation of one side wall is also undermined the whole of its length, and as it in some places overhangs the precipice formed by the waste of the sea, and as the castle is not situated upon a rock, but upon hard loamy soil, this side must inevitably fall in a few years.

"Many huge fragments of the wasted walls are scattered upon the shore, under the cliff from whence they have fallen; and notwithstanding the concussion they have received in falling from a great height, and the frequent surges of the sea, they are as firm as ever, and in many places exhibit the shape of the edifice.

"The corners and doorcases of the guard-towers, the buttresses, window-frames, and several parts of the main tower, are constructed with red freestone; but all the other parts of the walls which in general are about six or seven feet in thickness, are formed of round stones collected from the adjacent shores. The inside of the walls has been constructed with small stones, and plenty of fluid mortar to fill the interstices.
