The Sea-ward Tower was a tower situated in or near Dol Amroth. In Sindarin, the name of the tower was Tirith Aear. A verse recorded in the Red Book tells of "one slow bell high in the Seaward Tower".J.R.R. Tolkien, "The Man in the Moon Came Down Too Soon", in The Adventures of Tom Bombadil</ref>
The Sea-ward Tower is conceived to have been constructed as a refuge for the Elves of Edhellond by the Sinda lord Amroth, between 1600 and 1620 of the Second Age. Tirith Aear is further said to have been used by Galadriel, who installed "a huge bronze bell in its highest chamber in T.A. 1". A full layout of the tower is provided.
