The inner, ballium is surrounded by a high circular wall, which consists of an uninterrupted line of bastions, some semi-circular and others square.--The whole of this part of the castle remains nearly perfect. There are also traces of extensive foundations in various, directions, and of great out-works. Château Gaillard was in fact a citadel, supported by numerous smaller fortresses, all of them communicating with the strong central hold, and disposed so as to secure every defensible post in the neighborhood. The wall of the outer ballium, which was built of a compact white and grey stone, is in most places standing, though in ruins. The original facing only remains in those parts which are too elevated to admit of its being removed with ease.--Beneath the castle, the cliff is excavated into a series of subterraneous caverns, not intended for mere passages or vaults, as at Arques and in most other places, but forming spacious crypts, supported by pillars roughly hewn out of the living rock, and still retaining every mark of the workman's chisel. It will afford some satisfaction to the antiquary to find, that the present appearance of the castle corresponds in every important particular with the description given by Willelmus Brito, who beheld it within a few years after its erection, and in all its pride. Every feature which he enumerates yet exists, unaltered and unobliterated:-- "Huic natura loco satis insuperabile per se Munimeu dederat, tamen insuperabiliorem Arte quidem multa Richardus fecerat illum. Duplicibus muris extrema clausit, et altas Circuitum docuit per totum surgere turres, A se distantes spatiis altrinsecus æquis; Eruderans utrumque latus, ne scandere quisquam Ad muros possit, vel ab ima repere valle. Hinc ex transverso medium per planitiei Erigitur murus, multoque labore cavari Cogitur ipse silex, fossaque patere profunda, Faucibus et latis aperiri vallis ad instar; Sic ut quam subito fiat munitio duplex Quæ fuit una modo muro geminata sequestro. Ut si forte pati partem contingeret istam Altera municipes, queat, et se tuta tueri. Inde rotundavit rupem, quæ celsior omni Planitie summum se tollit in aera sursum; Et muris sepsit, extremas desuper oras Castigansque jugi scrupulosa cacumina, totum Complanat medium, multæque capacia turbæ Plurima cum domibus habitacula fabricat intus. Umboni parcens soli, quo condidit arcem. Hic situs iste decor, munitio talis honorem Gaillardæ rupis per totum prædicat orbem." The keep cannot be ascended without difficulty. We ventured to scale it; and we were fully repaid for our labor by the prospect which we gained. The Seine, full of green willowy islands, flows beneath the rock in large lazy windings: the peninsula below is flat, fertile, and well wooded: on the opposite shores, the fantastic chalky cliffs rise boldly, crowned with dark forests.
