Dol Amroth was a stronghold on a promontory of Belfalas, situated in the coastal region of Gondor. It was named after Amroth, King of Lórien, who had drowned nearby in the Bay of Belfalas. (You can read more about the story of Amroth here.)
There was an ancient Elvish port near Dol Amroth named Edhellond (Elf-haven), and there was a small settlement of Silvan Elves there from Lórien. It was said that the princely house of Dol Amroth had ‘a special Elvish strain’.
‘The legend of the prince’s line was that one of their earliest fathers had wedded an Elf-maiden’, probably Mithrellas, of the Silvan race. The people of Dol Amroth were described as dark-haired ‘tall men and proud with sea-grey eyes’. The first prince of Dol Amroth was Galador, and according to legend, he married Mithrellas. The twenty-second prince of Dol Amroth was Prince Imrahil, whom Legolas saw as ‘one who had elven-blood in his veins’. Prince Imrahil’s sister, Finduilas, married Denethor II, and was the mother of Boromir and Faramir.
As Dol Amroth was a coastal city, it was occasionally attacked by the Corsairs of Umbar. The fifteenth prince of Dol Amroth was slain in battle against the sea raiders in T.A. 2746.
