Great for history-lovers. Originally built for England’s King John in 1210, it was twice besieged in the 17th century (”The Siege of Athlone”) before finally being captured by the Williamites. The closing decades of the seventeenth century were among the most turbulent in this country’s history. It is not surprising then to realise that the most dramatic events in the history of Athlone occurred during the Williamite and Jacobite Wars.

In 1690 the town was besieged by 10,000 Williamite troops under the command of General James Douglas. The Jacobite force present in the town, under the command of the Governor of Athlone, Colonel Richard Grace, resolutely refused to surrender. Following a week long siege the Williamites retreated.

Athlone enjoyed a year of relative peace until June of 1691 when the town was again besieged by the Williamites. This time it was the full Williamite Army of almost 25,000 men led by the Dutch General, Godard de Ginkel which laid siege to the town. The Williamites quickly captured the Leinster town but the jacobites broke down the bridge to stem their advance. Under the command of the French genera, the Marquis de St. Ruth, they courageously resisted all attempts to repair it. A brave Sergeant of Dragoons, Custume by name, lost his life in his attempts to dislodge the vigorous repair works and by so doing became a folk hero celebrated in poetry and story. Ginkels guns, in one of the heaviest bombardments in Irish history, fired 12,000 cannonballs into the tiny Connacht town badly damaging Athlone Castle and reducing other buildings to rubble. The Williamites discovered a fording point and in a surprise attack crossed the river and captured the Castle.
