Roscommon is the county that sits in the middle of everything and gets noticed by almost nobody. It borders eight other counties, has no coastline, no mountains to speak of, and no signature attraction that pulls the coach tours. What it has is Rathcroghan - the ancient capital of Connacht and one of the most important archaeological landscapes in Europe, with over 240 recorded monuments - and almost nobody there to see them.
Strokestown Park House and the National Famine Museum form one of the most powerful heritage experiences in Ireland. Lough Key Forest Park near Boyle is a genuinely excellent family day out. The Shannon forms the eastern border and the river towns along it have a quiet charm. Roscommon is not trying to sell you anything, which is part of what makes it worth visiting.
Know before you go
Roscommon is flat, rural, and quiet. You need a car. The N5 and N6 cut through the county connecting Dublin to the west, so you may have driven through it without realising. Rathcroghan requires some imagination - these are earthworks in fields, not reconstructed buildings. The guided tours from the Rathcroghan Visitor Centre transform the experience.
