No. 54 Merrion Square forms part of the eighteenth-century square developed by the Fitzwilliam Estate. This building is an elegant and well-proportioned house that makes a strong contribution to the early streetscape character of Merrion Square. The relatively modest fa├žade is enlivened by its ornate Ionic doorcase with an elaborate fanlight and leaded geometric sidelights, while the railings and balconettes provides additional features of visual and craft interest. Good ceilings (Casey, 2005). Nos. 53-54 was adapted as a convent, St. Mary Reparatrice, for which a chapel was installed in 1939. The building and its intact setting details contribute significantly to the intact appearance of this important architectural set-piece. The square is one of the best-preserved Georgian streetscapes in Ireland. The north, east and south sides are lined with terraced houses of eighteenth and early nineteenth-century date, while the west side is terminated by the garden front of Leinster House. The houses maintain a relatively uniform building height and design, attributed to standards promoted in Fitzwilliam's leases. Individuality was introduced through the design of doorcases, window ironwork and interior decorative schemes.
