The Sea-ward Tower or Seaward Tower, also called Tirith Aear, was a tower situated in or near Dol Amroth.
In a poem recorded in the Red Book of Westmarch, a single "slow bell" that was "high in the Seaward Tower" rang solemnly at an "unseemly hour" to announce "the news of" the Man in the Moon's "moonsick cruise" aboard "a fisherman's boat" in the Bay of Belfalas.
