Carn Dum

Carn Dûm was the chief fortress of the realm of Angmar and the seat of its king. It was located at the western end of the Mountains of Angmar, the north-western extension of the Misty Mountains.
== History ==
In T.A. 1409 a great host from Angmar invaded and ravaged Cardolan and killed its last prince. Carn Dûm remained capital of Angmar since around T.A. 1300 to T.A. 1973, being briefly replaced by Fornost the last two years. 
In 1974, the combined armies of Gondor, Lindon and Arnor crossed the river Lune and defeated the forces of Angmar in a great battle on the plain between Nenuial and the North Downs. The Witch-king and his surviving forces fled northwards toward Angmar, but they were overtaken by the cavalry of Gondor with prince Eärnur at their head and cut off by a force led by Glorfindel that came from the south out of Rivendell before before they were able to reach shelter in Carn Dûm. The Witch-king was able to flee, but the remaining forces of Angmar were utterly defeated and no man or orc of the realm of Angmar remained west of the Mountains. As a consequence, it is possible that Carn Dûm was destroyed. It is also possible that Carn Dûm was repopulated after 2480, when Orcs began making secret strongholds in the Misty Mountains, but the fate of Carn Dûm is not mentioned in the Annals of the Kings and Rulers or in the Tale of Years.
On September 28 of 3018 While Merry was trapped with Frodo in a Barrow, he had a dream that he and others were attacked and defeated by the men of Carn Dûm at night and that his heart had been pierced with a spear. Some say that this barrow was the grave of the last prince of Cardolan. It is possible that he dreamt of what happened to the last prince of Cardolan and his men.
It is ruled by Agandaûr, a descendant of the Black Númenóreans and a servant of Sauron.
