The rear or gorge wall is not exactly a curtain to the flanking towers. It is placed a little outside of them, on the edge of the ditch; and between it and the east tower was the gateway, the special and independent entrance of the outwork. The north side is gone, but the other side shows the springing of the portal arches and a square portcullis groove. In this gorge wall, not far from the gate, is a large arch, corresponding to that already mentioned in the outer-ward wall. This was, no doubt, a way of communication between the castle and the earthwork. This ditch was crossed by a wall at the east end, which connected the two works and protected the bridge. The west end is filled with ruins. There are now no traces of buildings in the outwork.
The towers of the outwork are of great strength, and have been faced with ashlar. The front tower especially is strong, and does not appear ever to have been mined or breached. Also the rock beneath it is undisturbed. Possibly the breach spoken of at the siege was in the adjacent curtain on the east.
In the rear of this work is the ditch already described, and along its front and flanks is another ditch, proper to the outwork, and the most formidable of all the defences. It is above 30 feet wide, and at the advanced point, where the ground rises, above 40 feet deep. The scarp and counterscarp are vertical.
Besides these regular works are others of a less regular but very formidable character, on the west side. This face of the rock towards the Seine, steep naturally, has been scarped and defended by art. Half-way down the slope is a round tower, connected, it is said, with the work above, by a gallery cut in the chalk. From the tower a wall descended to the river, so that the approaches on this side and the road between the hill and the river were effectually commanded. This wall seems to have terminated on the river bank, in a pier of which traces remain, and which supported one end of a strong dam or weir of piles, which extended across the river, and was part of the original work of Cœur-de-Lion. Several other works were stepped into the rocky slope, and especially covered the west side.
The weir crossed above the island, called formerly D’Andelys, upon which was the octangular fort, erected also by Richard, and of which traces remain. The bridges from this island, either way, to the banks, were of timber, and have left no trace behind.
Finally are to be mentioned the fortifications of the lesser Andelys, now destroyed, and the lake, fed by the waters of the Gambon, and which washed the walls of Great Andelys, and completely enveloped the lower town. These additional defences are now destroyed and the lake is drained and filled up, but indications remain sufficient to verify the detailed description of Guillaume le Breton, and to justify M. Deville in his description, and M. le Duc, in his restorations, advanced under the excellent articles “Château” and “Donjon” in his “Dictionary.”
THE CASTLE OF CHRISTCHURCH, HANTS.
THE town, castle, and priory of Christchurch are placed upon the south-eastern point and edge of a tongue of moderately-high ground, which intervenes between the Stour on the west and the Avon on the east. The two rivers of Dorset and Wilts meander like their prototype,
