Though Hugh Lane struggled to find a permanent home for his Dublin gallery, the project remained afloat and exists today as the Hugh Lane gallery. Their digitized collection includes paintings from Lane's controversial bequest, which today are shared between Hugh Lane Gallery and London's National Gallery. This link will allow you to look at these digitized works. The website also features a digitized collection of works described in another Yeats poem, "The Municipal Gallery Revisited."
