Baile an Chaisleáin · Co. Roscommon

River Suck town. Clonalis House holds the O'Conor archive - one of Ireland's oldest noble families.

Castlerea is a town on the River Suck in west Roscommon, population 2,350. It sits on the banks of the Suck and the Francis, both tributaries of the Shannon. It is not on the main road, which is why it has stayed quiet.

The reason to come is Clonalis House. It is the ancestral seat of the O'Conor Don, who are the direct descendants of Cathal Crobhdearg Ua Conchobair, King of Connacht. The O'Connors are one of the oldest Gaelic noble families in Europe. Their genealogy is verifiable and they held the throne of the Kingdom of Connacht up until 1475. Two of their number - Turlough Mór O'Conor (1088-1156) and Rory O'Conor (1116-1198) - achieved the undisputed High Kingship of Ireland.

The house was built in 1878 to replace a 17th-century house. The O'Conor Archive contains over 100,000 manuscripts, many in Irish, some dating back to the sixteenth century. The harp of O'Carolan - the last of the great wandering Irish bards - is here. There is a library of over 7,000 books. The estate has been in continuous possession of the family for over 1,500 years. This is not tourism. This is genealogy you can walk into.

1,500 years

The O'Conor family

The O'Conor Don are descendants of Cathal Crobhdearg Ua Conchobair, King of Connacht. Their genealogy extends back nearly 1,500 years and is one of the oldest documented lineages in Europe. The family held the throne of the Kingdom of Connacht until 1475. At the height of their power in the twelfth century, two family members achieved the undisputed High Kingship of Ireland: Turlough Mór O'Conor (1088-1156) and Rory O'Conor (1116-1198). The estate at Clonalis has been in continuous possession of the family throughout this entire period - an unbroken chain of ownership spanning fifteen centuries. In the modern era, the family still regards themselves as the last remnant of the ancient Kingdom of Connacht.

Built 1878

Clonalis House

Charles Owen O'Conor Don built the present house in 1878 to replace a ruined seventeenth-century house on the estate. The house was designed to be a statement of continuity - a new building on the same land, housing the same archive, stewarding the same history. The O'Conor Archive contains over 100,000 manuscripts, many in Irish, dating back to the sixteenth century. Among the collections are an important series of family portraits and the harp of O'Carolan, the last of the wandering Irish bards. The library contains more than 7,000 books.

Suck and Francis

The rivers

Castlerea is built at the confluence of the River Suck and the River Francis, both tributaries of the River Shannon. The rivers shaped settlement, powered mills, and define the landscape. The Suck flows south and west from Lough Allen, through Carrick-on-Shannon, and joins the Shannon at Castlerea. The Francis comes from the northwest. The confluence is marked by the town.
