The castle was originally built on land that had been taken from the Augustinian Priory in Roscommon.
The gatehouse features a twin-towered design that was highly advanced for its time in the late 13th century.
During the 16th century, the castle was held by the O'Connor Don family before being granted to Sir Nicholas Malby.
The castle was dismantled in the mid-17th century to prevent it from being used as a defensive stronghold by insurgent forces.
Excavations at the site have unearthed medieval pottery fragments and iron artifacts consistent with military occupation.
Roscommon Castle is a 13th-century Norman fortress located on the outskirts of Roscommon town. Built in 1269 by Robert de Ufford, the Justiciar of Ireland, the structure features a large rectangular courtyard flanked by four D-shaped towers. The castle underwent significant architectural modifications in the 13th and 14th centuries, particularly regarding its gatehouse. It was the site of frequent conflict between the Anglo-Norman settlers and the O'Connor kings of Connacht. The site changed hands multiple times throughout the medieval period before falling into disrepair following the Cromwellian wars in the 17th century. Today, the ruins are managed by the Office of Public Works and remain open to the public as a free-access historical site. The site is situated adjacent to Loughnaneane Park, which provides expansive green space around the castle grounds.
