Osgiliath was the first capital city of Gondor. During the War of the Ring, the abandoned city gained strategic importance as a crossing point over the Anduin, both for the Men of Gondor and Orcs of Mordor. At the heart of Osgiliath was a great stone bridge over the river. On the bridge was a tower containing the famous Dome of Stars, which housed the city’s palantír. Another important building (or possibly the same one) was the Great Hall, which initially served as a throne room.
