"This city was once the jewel of our kingdom. A place of light, and beauty, and music. And so it shall be once more!"
Taken from Boromir's speech, in the movie Two Towers, to his soldiers after they managed to take back Osgiliath from Sauron, before the events in the Fellowship of the Ring. Unfortunately, the city was taken back by Sauron after Boromir died in Amon Hen.
