A brief history: In mythological Ireland, Rathcroghan, in present-day Roscommon, was the seat of Queen Maebh (Maeve), the Kings of Connacht, and later the High Kings of Ireland.
The name Roscommon comes from the Irish 'Ros' meaning a wooded, gentle height and 'Coman', the name of the county's famous saint and the first bishop of the see, Coman mac Faelchon, who built a monastery in Roscommon in the fifth century.
Roscommon was officially established in 1585, when the Tudors reinstated the land division of Connacht. It is outlined by water, with Lough Key in the North, the River Shannon and Lough Ree to the East, the River Suck to the West.
In 2008 it was revealed that statistically, Roscommon has the longest life expectancy of any county on the island of Ireland.
There is also a County Roscommon in Michigan.
Key attractions: Lough Key in north Roscommon has 32 islands – coincidentally, the number of counties on the island of Ireland. Nearby is Lough Key Forest Park.
