DescriptionA hilly region where the White Towers were built
InhabitantsElves, Men, then Hobbits

Elostirion was the tallest and westernmost of the three White Towers that stood on the Tower Hills, built by Gil-galad for Elendil. It stood alone upon a green mound.[1]

It held one of the palantíri of Arnor, which did not communicate with the rest, but looked only westward across the Sundering Seas to Tol Eressëa. It was the last stone of Arnor until it was removed at the very end of the Third Age.[2]

Although no Hobbit was known to ever climb it, those of the Westfarthing had the tradition that from its top one could see as far as the Sea,[1] perhaps echoing the knowledge of the palantír there.
