White Towers
From Tolkien Gateway
The White Towers were built by Gil-galad as a gift to Elendil, perhaps after the founding of Arnor (Second Age 3320).
The tallest of the three was called Elostirion and a palantír was kept there.
They were sometimes the destination of pilgrimage by Wandering Companies of Elves who would gaze to Valinor through the palantír. Such a band was led by Gildor Inglorion.
