p. 215. “(Fitzwilliam, V/DEP; Herbert, Pembroke, E/PB) An early C18 house which appears to have consisted of three rather similar blocks of more or less equal size arranged to form an open-fronted court. Only one block now survives; it is square, rather low, of two storeys with a dormered attic. Five bay front, three bay pedimented breakfront. Very high pediment with fanlighted lunette window; central round-headed window below, longer than the window either side of it. Four bay side-elevation, round headed windows in upper storey; two lunette windows and two rectangular sash windows below. The seat of the Viscounts Fitz-William, from whom it passed by inheritance early C19 to the Earls of Pembroke, together with the Fitzwilliam Dublin estate; which includes Merrion Square and Fitzwilliam Square.”
