The Winding Stair is a volume of poems by Irish poet W. B. Yeats, published in 1933. It was the next new volume after 1928's The Tower. (The title poem was originally published in 1929 by Fountain Press in a signed limited edition, which is exceedingly rare.) The title refers to the staircase in the Thoor Ballylee castle which Yeats had purchased and lived in with his family for some time. Yeats saw the castle as a vital connection to the aristocratic Irish past which he admired. The phrase "winding stair" is used in the book's third poem, "A Dialogue of Self and Soul."
