Athlone Castle
Athlone Castle is a stone castle on the Shannon in Athlone, County Westmeath, Ireland, with origins in the 12th–13th centuries and extensive later remodelling. The site incorporates a central polygonal keep surrounded by a curtain wall with squat three-quarter round (drum) towers and later barrack buildings; it now houses a visitor centre and museum.

As it stood in 1810
What Athlone Castle looked like in its prime.
A low, robust grey-stone silhouette: a central polygonal keep rising from a man-made motte, encircled by a high curtain wall punctuated by squat three-quarter round drum towers with dark coping. The masonry is irregular ashlar and rubble limestone with visible weathering and patched repairs; the parapet is broad and adapted for artillery with gun-embrasures and pistol-loops. The castle fronts directly onto town streets and the River Shannon, with a late-Georgian two-storey barrack façade adjoining the walls.
Its story
The story of Athlone Castle.
Tairrdelbach's Timber Castle to King John's Stone Tower, 1129–1210
The earliest recorded castle at Athlone was a wooden structure raised in 1129 by Tairrdelbach Ua Conchobair, king of Connacht, possibly on the same site as the castle standing today. The stone castle that survives was built in 1210 for King John by his Irish justiciar, Bishop John de Gray of Norwich, to defend the river crossing at Athlone and give the Norman advance into Connacht a bridgehead. It took the form of a free-standing polygonal tower raised on a motte, newly built or already existing, and — though much altered — that tower still forms the castle's central keep. In its early years the castle is thought to have had the protection of a fosse or moat.
Curtain Wall and Drum Towers, c.1276–1547
The castle was substantially refortified around 1276, when the motte was enclosed by a curtain wall with three-quarter-round drum towers at its corners; heavily rebuilt since, these still stand. Sir William Brabazon reconstructed the castle again in 1547.
The Williamite Sieges and Napoleonic Rearming, 1690–1940s
The external walls and towers took heavy fire during the Sieges of Athlone of 1690–91, and lightning destroyed part of the castle in 1697. It was extensively remodelled again during the Napoleonic era, when it was modernised and adapted for artillery — leaving its squat drum towers somewhat reminiscent of the Martello towers built along the Irish coast in the same period.
A five-bay, two-storey barrack block overlooking Main Street, dating to around 1810, housed the officers' and soldiers' quarters recorded on the 1874 Ordnance Survey map alongside a guardhouse, cookhouse, kitchen and drawbridge. Surviving details include a sally-gate opening in the wall above the Shannon, a bow-loop from the castle's archer era facing Castle Street, and gun-embrasures and pistol loops covering the entrance ramp; the drawbridge itself survived until the 1940s.
Museum and Visitor Centre, 1967–2012
The keep is a National Monument. Having formed part of Athlone's defences for 750 years, the castle became home to a museum run by the Old Athlone Society in 1967, and a modern visitor centre followed under Athlone Urban District Council in 1991; it has been managed by Athlone Arts and Tourism since 2012. A multimillion-euro renovation saw it reopen in 2012 with eight chronological and thematic exhibition spaces, including 3D maps, audio-visual installations and illustrations by Victor Ambrus, known for his work on the archaeology programme Time Team.
