Kilbrogan House was built in 1818 on the Bandon estate of William Cavendish, 6th Duke of Devonshire.
[1] Remaining original features include ornate plaster work and exterior limestone steps.
[1] Originally owned by the Devonshire estate and let to several tenants, in the 1890s the freehold was sold to Richard Wheeler Doherty.
[citation needed] Doherty leased the house to Joseph Brennan, whose business interests included a local bakery, brewery, flour mill and an electric company which supplied electricity to Bandon from 1919 to 1939.
[1] In October 1920, during the Irish War of Independence, much of Bandon (including Brennan's businesses and Kilbrogan House) was attacked by British soldiers as part of a series of indiscriminate reprisals following an IRA ambush at Ballinhassig.
