The Niland Collection, displayed on a rotational basis, contains some 200 works by Jack Yeats, acquired by former county librarian Norah Niland. The collection of Irish Modern Art includes paintings by George Russell, Maurice McGonigal, Norah McGuinness, Estella Solomons, Paul Henry, Augustus John and Seán Keating. The old manse (1851) houses the Yeats Memorial, a collection of manuscripts, photographs and letters.
