Shanbally Castle was built around 1812 and was the largest of Nash's Irish country houses. It was designed in the Gothic style and set within a picturesque Reptonian demesne, reflected Nash and Repton's earlier collaboration, Luscombe Castle, Devon. After a valiant, but unsuccessful attempt by Hon. Edward Sackville-West (5th Baron Sackville) to rescue the castle, it was demolished in 1957 (M. Bence-Jones, Burkes Guide to Country Houses: Vol. I Ireland, London, 1978, p. 257; R. MacDonnell, The Lost Houses of Ireland, London, 2002, pp. 191-196).
