County Roscommon is a county in the west of Ireland, located in the province of Connacht. The county takes its name from Roscommon town and from the Irish form Contae Ros Comáin, a placename traditionally linked with the early Christian figure Comán. Roscommon is characterized by a predominantly rural landscape of farmland, bog, woodlands and inland waterways.

Geography and landscape

Roscommon lies inland and contains low drumlin country, river plain and several notable loughs. The River Shannon and associated lakes such as Lough Key and Lough Ree are important natural features that shape the county’s ecology and recreation. Much of the land is used for agriculture or remains as peatland and forestry, giving Roscommon a sparse settlement pattern compared with Ireland’s urban areas.

History and heritage

The county has deep historical roots, with archaeological sites ranging from prehistoric monuments to medieval ruins. Rathcroghan (Ráth Cruachan), a complex of ancient royal sites associated with the kings of Connacht and Irish mythology, lies within the county. Other historic remains include monastic ruins and castle sites that testify to Roscommon’s role in medieval and early modern Ireland.

Economy and society

Roscommon’s economy is largely based on agriculture, forestry and rural enterprises, supplemented by manufacturing in small towns and services tied to tourism. Population is concentrated in market towns and villages; according to the 2011 Irish census the county had 65,065 inhabitants. Community life often centers on local festivals, sporting clubs and cultural heritage projects.
