County Roscommon is named after the county town of Roscommon. Roscommon comes from the Irish Ros meaning a wooded, gentle height and Comán, the first abbot and bishop of Roscommon who founded the first monastery there in 550 AD.[5]
County Roscommon has an area of 2,548 square kilometres (984 sq mi).[3]Lough Key in north Roscommon is noted for having thirty-two islands. The geographical centre of Ireland is located on the western shore of Lough Ree in the south of the county.[6]
Roscommon is the third largest of Connacht's five counties by size and the second-smallest in terms of population. It ranks 11th in size of Ireland's 32 counties, but 26th in terms of population, making it the 3rd most sparsely populated county after Leitrim and Mayo. The county borders every other Connacht county: Galway, Mayo, Sligo, and Leitrim, as well as three Leinster counties: Longford, Westmeath, and Offaly. In 2008, a news report said that statistically, people from Roscommon have the longest life expectancy of any county on the island of Ireland.[7]
Seltannasaggart, which is located along the northern border with County Leitrim, is the tallest point in County Roscommon, measuring to a height of
428 m (1,404.20 ft).[8]
County Roscommon as an administrative division has its roots in the Middle Ages. With the conquest and division of the Kingdom of Connacht, those districts in the east retained by King John as "The King's Cantreds" covered County Roscommon, and parts of East Galway. These districts were leased to the native kings of Connacht and eventually became the county. In 1585 during the Tudor re-establishment of counties under the Composition of Connacht, Roscommon was established with the South-west boundary now alongside the River Suck.
John O'Donovan (1806–1861), historian and scholar, visited County Roscommon in 1837, while compiling information for the Ordnance Survey. Entering St Peter's parish in Athlone in June 1837, he wrote, "I have now entered upon a region totally different from Longford, and am very much pleased with the intelligence of the people." However, he had major problems with place-names. He later wrote, "I am sick to death's door of lochawns, and it pains me to the very soul to have to make these remarks, but what can I do when I cannot make the usual progress? Here I am stuck in the mud in the middle of Loughs, Turlaghs, Lahaghs and Curraghs, the names of many of which are only known to a few old men in their immediate neighbourhood and I cannot give many of them utterance from the manner in which they are spelled."[14][15]
The 1898 Act also divided the county into the rural districts of Athlone No. 2, Ballinasloe No. 2, Boyle No. 1, Carrick-on-Shannon No. 2, Castlerea, Roscommon, and Strokestown.[16] The rural districts were abolished in 1925.[17]Boyle and Roscommon were administered locally by town commissioners.[18] Roscommon town commissioners were abolished in 1927. After becoming a town council in 2002,[19] in common with all other town councils in Ireland, Boyle Town Council was abolished under the Local Government Reform Act 2014.[20]
