Many houses there were, chambers, halls, and passages, cut and tunnelled back into the walls upon their inner side, so that all the open circle was overlooked by countless windows and dark doors. Thousands could dwell there, workers, servants, slaves, and warriors with great store of arms; wolves were fed and stabled in deep dens beneath. The plain, too, was bored and delved. Shafts were driven deep into the ground; their upper ends were covered by low mounds and domes of stone, so that in the moonlight the Ring of Isengard looked like a graveyard of unquiet dead. For the ground trembled. The shafts ran down by many slopes and spiral stairs to caverns far under; there Saruman had treasuries, store-houses, armouries, smithies, and great furnaces. Iron wheels revolved there endlessly, and hammers thudded. At night plumes of vapour steamed from the vents, lit from beneath with red light, or blue, or venomous green.
To the centre all the roads ran between their chains. There stood a tower of marvellous shape. It was fashioned by the builders of old, who smoothed the Ring of Isengard, and yet it seemed a thing not made by the craft of Men, but riven from the bones of the earth in the ancient torment of the hills. A peak and isle of rock it was, black and gleaming hard: four mighty piers of many-sided stone were welded into one, but near the summit they opened into gaping horns. their pinnacles sharp as the points of spears, keen-edged as knives. Between them was a narrow space, and there upon a floor of polished stone, written with strange signs, a man might stand five hundred feet above the plain. This was Orthanc, the citadel of Saruman, the name of which had (by design or chance) a twofold meaning; for in the Elvish speech
A strong place and wonderful was Isengard, and long it had been beautiful; and there great lords had dwelt, the wardens of Gondor upon the West, and wise men that watched the stars. But Saruman had slowly shaped it to his shifting purposes, and made it better, as he thought, being deceived – for all those arts and subtle devices, for which he forsook his former wisdom, and which fondly he imagined were his own, came but from Mordor; so that what he made was naught, only a little copy, a child's model or a slave's flattery, of that vast fortress. Armoury, prison, furnace of great power, Barad-dur, the Dark Tower, which suffered no rival, and laughed at flattery, biding its time, secure in its pride and its immeasurable strength.
This was the stronghold of Saruman, as fame reported it; for within living memory the men of Rohan had not passed its gates, save perhaps a few, such as Wormtongue, who came in secret and told no man what they saw.
Now Gandalf rode to the great pillar of the Hand, and passed it: and as he did so the Riders saw to their wonder that the Hand appeared no longer white. It was stained as with dried blood; and looking closer they perceived that its nails were red. Unheeding Gandalf rode on into the mist, and reluctantly they followed him. All about them now, as if there had been a sudden flood, wide pools of water lay beside the road, filling the hollows, and rills went trickling down among the stones.
At last Gandalf halted and beckoned to them; and they came, and saw that beyond him the mists had cleared, and a pale sunlight shone. The hour of noon had passed. They were come to the doors of Isengard.
But the doors lay hurled and twisted on the ground. And all about, stone, cracked and splintered into countless jagged shards, was scattered far and wide, or piled in ruinous heaps. The great arch still stood, but it opened now upon a roofless chasm: the tunnel was laid bare, and through the cliff-like walls on either side great rents and breaches had been torn; their towers were beaten into dust. If the Great Sea had risen in wrath and fallen on the hills with storm, it could have worked no greater ruin.
The ring beyond was filled with steaming water: a bubbling cauldron, in which there heaved and floated a wreckage of beams and spars, chests and casks and broken gear. Twisted and leaning pillars reared their splintered stems above the flood, but all the roads were drowned. Far off, it seemed, half veiled in winding cloud, there loomed the island rock. Still dark and tall, unbroken by the storm, the tower of Orthanc stood. Pale waters lapped about its feet.
