Roscommon is home to Kings and Castles, incredible archaeological sites and historical ruins that would make anyone stop and gaze in awe of these monumental sites that are so unique to Roscommon.
Roscommon was named after Coman mac Faelchon who had come to Roscommon and built a monastery in the 5th century on the east bank of the River Suck, at a wood (ros) which was called after him (Ros Comain).
Following the rich heritage of Roscommon going back hundreds of years, you can follow Roscommon Town interactive trails and listen to stories and facts about the ruins left behind after all these centuries. Luckily many of these buildings have been cared for and are still in use today. The Interactive Heritage Tour guides you to ten wonderful historic sites in Roscommon Town.
Roscommon Castle
A 13th century Norman castle which was once home to the King of Connaught. In 1641, it was obtained by the Parliamentarian faction and then confederate Catholics, under Preston, captured it in 1645. From then, it remained in Irish hands until 1652, when it was partially blown up by Cromwellian ‘Ironsides’, who then had all the fortifications dismantled. The castle was burned down in 1690 and ultimately fell into decay. Take a walk inside and explore the ruins and see for yourself the great castle it once was.
Sacred Heart Church
The Sacred Heart Catholic Church is notable for many reasons, as not only does it boast a 53m-high spire, but its interior also features colourful mosaics on the floor and walls, some inspired by Botticelli and Michelangelo. Roscommon Town’s Sacred Heart Catholic Church was designed by Walter Doolin and P.J. Kilgallon and opened in 1903.The stunning church has many features that make it worth a visit. The structure’s 53m-high spire extends toward the sky, while inside there are many beautiful mosaics, including some created by Salviati of Venice. Other colourful mosaics decorating the walls and floor take inspiration from Botticelli and Michelangelo. Outside, there is a sunken grotto for an introspective visit.
