The Tower is a collection of poems by William Butler Yeats, published in 1928. The title refers to Ballylee Castle, an old Norman tower in the west of Ireland which Yeats purchased in 1917 and renovated for use as a summer residence. The book includes some of Yeats' most famous poems, including "Sailing to Byzantium" and "Leda and the Swan". The poems in The Tower are often characterized by their use of symbolism, myth, and allegory, and they explore themes such as love, loss, and the search for meaning in a chaotic world.
