Caras Galadhon (pronounced /ˈkaras ˈgalaðon/) was the chief city of Lórien.
Caras Galadhon was in the Naith of Lórien, in the heart of the Silvan Elven realm. It was built in the middle of, on top of, and out of the mallorn trees that Galadriel had brought with her from Valinor, and was the residence of Celeborn and Galadriel.
In some printings of The Lord of the Rings, Caras Galadhon may be misspelled as Caras Galadon.
During the Fourth Age, after Galadriel had left Lórien, Caras Galadhon was ruled by a lonely Celeborn as capital of a Lórien which now spanned both sides of the river Anduin, but at some point during the age he left for Valinor was well, and Caras Galadhon slowly became depopulated.
