Mithlond

In the fiction of J.R.R. Tolkien, the Mithlond or the Grey Havens was a haven (seaport) on the Gulf of Lune[?] in the northwest of Middle-earth.

Warning: Wikipedia contains spoilers

Built by the Elves of Lindon at the beginning of the Second Age, it was afterwards used by the Elves to leave Middle-earth for Valinor. Círdan the Shipwright lived there.

Bilbo Baggins and Frodo Baggins also went to Valinor from the Grey Havens, and a family tradition held that Sam Gamgee (having been himself a Ringbearer, albeit briefly) did likewise, in S.R. 1484.
