Castle Richmond (1860) is a novel by Anthony Trollope. It is set in southwestern Ireland at beginning of the Irish famine. Castle Richmond is situated on the banks of the Blackwater River in County Cork. The plot features the competition of two Protestant cousins of English origin, Owen and Herbert Fitzgerald, for the hand of Clara Desmond, the noble but impoverished daughter of the widowed Countess of Desmond, providing the novel's principal dramatic interest. Castle Richmond was the first of several novels by Trollope in which bigamy played an important role. The Irish famine and efforts by authorities to mitigate its effects are the subject of many scenes and the object of abundant commentary throughout. The famine also occasions more explicit religious commentary than is typical in novels by Trollope.
