Emo Court
One of the few houses James Gandon designed, finished over seventy years by three architects, with a Coade stone dome.
Updated 19 October 2026
Emo Court was begun in 1790 for John Dawson, first Earl of Portarlington, to a design by James Gandon - the architect of the Custom House and the Four Courts, and this is one of the few country houses he designed. The earl died in 1798 and the work stalled; it was continued by Lewis Vulliamy in the 1830s and completed by William Caldbeck in the 1860s, so the building spans three architects and seventy years. The rotunda beneath the copper dome is the set piece, lined with scagliola columns imitating marble. The Jesuits owned it as a novitiate from 1930 and painted over much of the decoration; Major Cholmeley Dering Cholmondeley Harrison bought it in 1969 and spent decades restoring it before giving it to the state in 1994. The grounds hold a large arboretum, a lake walk and an avenue of giant sequoias.
