Carn Dûm was the capital and chief fortress of the Witch-king's realm of Angmar. It was located at the western end of the Mountains of Angmar, the north-western extension of the Misty Mountains.
Around T.A. 1300 the chief of the Nazgûl came north to found the realm of Angmar, seeing hope in the disunion of Arnor while the southern kingdom of Gondor remained powerful. The Witch-king, as he became known, established Carn Dûm as his capital and populated it with Men of Darkness, Orcs, and other fell creatures.
Allying with the Hill-men of Rhudaur, the Witch-king in Carn Dûm sent forces that resisted the claim of Argeleb I of Arthedain of lordship over all of the former lands of Arnor. Clashes resulted and in 1356 Argeleb was slain. Arveleg I, the son of Argeleb, with strength from Cardolan and Lindon, repelled Rhudaur and Angmar from the Weather Hills and established an uneasy, fortified frontier.
In 1409 a stronger host commanded from Carn Dûm invaded Cardolan, surrounded Weathertop, and killed Arveleg. Again a coalition of Arthedain (now ruled by Araphor, son of Arveleg I) and Lindon contained the menace.
The kingdom of Arthedain perished in the Fall of Fornost in 1974. However, in 1975 the Witch-king's forces were driven north-east after the Battle of Fornost by the cavalry of Gondor and destroyed. Glorfindel drove off the Witch-king himself.
The host of Gondor left no Man or Orc alive west of the Mountains. On the eastern side in 1977 Frumgar led the Éothéod into the North and they drove the last remnants of Angmar away. At this time then Carn Dûm was wholly abandoned. While it is possible that Carn Dûm was repopulated after 2480, when Orcs began making secret strongholds in the Misty Mountains, its name was never mentioned again in any histories.
David Salo favours the Sindarin interpretation of "red valley", and provides the name as an example of the few Sindarin phrases where the adjective precedes the noun (others being Sarn Athrad and Sarn Gebir). Otherwise, neither words carn and dûm have been attested (carn could be a short form of caran possibly also seen in Carcharoth, "red maw")
Another suggestion, is that the name roughly translates as "mountain fortress" in Gaelic; although Tolkien uses Celtic elements for some translated Mannish names, this would have been the only instance where he uses Gaelic. It is unknown whether this is just coincidence or not.
