"The Tower" is a book of poems by W. B. Yeats, published in 1928. The Tower was Yeats's first major collection as Nobel Laureate after receiving the Nobel Prize in 1923. It is considered to be one of the poet's most influential volumes and was well received.
The title, which the book shares with the second poem, refers to Ballylee Castle, a Norman tower which Yeats purchased and restored in 1917. Yeats Gaelicized the name to Thoor Ballyllee, and it has retained the title to this day.
The book includes several of Yeats' most famous poems, including "Sailing to Byzantium," "Leda and the Swan," and "Among School Children."
