CASTLE MARTYR, County Cork, was built in the early 18th century by Henry Boyle, Speaker of the Irish house of commons, afterwards 1st Earl of Shannon.
The house was substantially enlarged by the 2nd Earl between 1764-71; and further re-modelled in the late Georgian period.
The entrance front is of two storeys and seventeen bays, comprising a five-bay recessed centre and giant pedimented portico between projecting wings.
The entrance front of the house overlooks a sheet of water which is part of the remarkable artificial river made before 1750 by the 1st Earl.
Castle Martyr was sold early in the 20th century to the Arnott family; then became a Carmelite college.
It now forms the nucleus of a luxury hotel resort.
Former town residence ~ 7 Connaught Place, London.
