Great Hall of Osgiliath

The hall in Osgiliath where Isildur and Anárion, joint rulers of Gondor under the High King Elendil, had their thrones. Its later history is uncertain, but presumably the Kings maintained it as their throne room and audience chamber, at least until the time of Tarondor, the twenty-seventh King, who removed the royal seat to Minas Anor.

The Great Hall was apparently connected with - or perhaps identical to - the famous Dome of Stars of Osgiliath, though the relations of the various halls and buildings in Osgiliath are not entirely clear. The only specific mention of the Great Hall is in The Silmarillion, which simply says that the thrones of Isildur and Anárion '...were set side by side in the Great Hall of Osgiliath' (Of the Rings of Power and the Third Age). In itself that tells us very little, but an additional clue comes from Tolkien's expanded index to The Lord of the Rings, where he describes the Dome of Stars as 'the great domed hall of old in Osgiliath'. That wording strongly implies that the Great Hall of Osgiliath actually was the Dome of Stars, though other readings are possible.
