This paper analyses Kate O'Brien's representation of Spain in Farewell Spain (1937), drawing on unpublished material. It argues that Farewell Spain , written during the Spanish Civil War, amounts to a travelogue with a hidden political agenda. While O'Brien's explicit pro-Republican statements were clearly written in response to the one-sided representations of the Spanish conflict in Ireland and Britain, the author deliberately distanced herself from other war-commentators by embedding her political comments in a highly subjective, sentimental travel book.
