No. 70 Merrion Square is an elegant Georgian house that forms part of the eighteenth-century square developed by the Fitzwilliam Estate. It has a relatively modest fa├žade that is enlivened by its ornate Ionic doorcase, while the metalwork of its railings and first floor balconettes provides additional features of visual and craft interest. It was the home of Joseph Sheridan Le Fanu (1814-1873), a writer best known for his ghost stories and mystery novels. He resided here from 1856 until his death in 1873. 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. The south side of the square was initially set in large plots of twelve leases; plots were leased consecutively from east to west up until the row was completed in 1791.
