No. 23 Merrion Square was built as part of the original development of the Georgian square. The north side of the square is set apart, as the majority of houses have granite rustication to the ground floor. Completed about 1765, It was built by Ralph Ward as one of a group of three with nos. 24 and 25. The relative plainness of the well-balanced fa├žade is relieved by the granite facing of the ground floor. The interior is embellished by fine Rococo plasterwork to the interior ceilings and cornices and good joinery. Laid out as part of the Fitzwilliam Estate, Merrion Square is one of the best-preserved Georgian streetscapes in Ireland. The north, east and south sides of the square are lined with terraced houses of eighteenth and 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.
