County Cavan in the north midlands of Ireland encompasses 193,500 hectares (478,148 acres) of land and water and is the nineteenth largest of Ireland’s thirty-two counties. Its landscape is characterised by small rounded hills, known as drumlins, interspersed with lakes. The hilly northwest of the county hosts a number of international tourism attractions including the Shannon Erne Waterway - Cavan flows north as well as south - and the Marble Arch Caves Global Geopark. The Geopark, which straddles the land boundary between the Republic of Ireland and Northern Ireland, is recognised by UNESCO to have an exceptional geological heritage. This publication, the 23rd volume in the History and Society series, edited by Jonathan Cherry and Brendan Scott with series editor William Nolan comprises twenty-nine chapters on this wonderful county. It is a co-operative enterprise that brings together a range of specialists from within and without the county to present its story. This study is one of the most important books published on the history of the county and is a magnificent work from tthe breadth and range of subjects covered to the quality and scholarship of the contributors.
