Athlone Castle
A castle at the centre of Ireland
In the town of Athlone, almost exactly in the middle of Ireland, a sturdy castle guards the banks of the mighty river Shannon. For centuries, Athlone was one of the most important places in the country, because the Shannon was a great natural barrier dividing the island, and Athlone held one of the few crossings. Whoever controlled Athlone Castle controlled the gateway between the east and the west of Ireland.
A Norman stronghold
Athlone Castle was built around 1210, in the reign of King John, to guard this vital crossing of the Shannon. Its distinctive many-sided keep, set within strong walls, rose beside the river and the bridge. From here, royal forces could control movement across the river and project power into the western province of Connacht.
For centuries the castle remained a key military stronghold, fought over and strengthened as the wars of Ireland came and went.
The great sieges
Athlone Castle's most dramatic moments came at the end of the 1600s, during the Williamite war between the supporters of the Catholic King James II and the Protestant King William III. Because Athlone guarded the crossing into the Jacobite-held west, it became a vital prize.
In 1690 and again, more fiercely, in 1691, great armies fought for Athlone. The town was bombarded with one of the heaviest cannonades seen in Ireland, and the defenders famously tore up the bridge over the Shannon and fought desperately to hold the river. The fall of Athlone in 1691 opened the way for the decisive defeat of the Jacobite cause at the nearby Battle of Aughrim soon after.
These sieges left their mark on the castle and made Athlone one of the most fought-over places in Irish history.
A castle rebuilt
After the wars, Athlone Castle continued in military use, and it was rebuilt and altered over the following centuries to mount cannon and serve as a barracks. This long military life helped the castle survive, though it changed its appearance over time.
In modern times the castle has been restored and turned into a lively visitor centre, with exhibitions, models and films telling the dramatic story of the sieges and of the town's place at the heart of Ireland.

Visitors can explore the castle's keep and walls, enjoy views over the Shannon, and discover the dramatic history of the great sieges through the interactive exhibitions in the visitor centre.
