Cromwell's Castle

Cromwell's Castle is a compact 17th-century fort built in the 1650s to defend Banagher Bridge at the crossing of the River Shannon. What makes it stand out is its military origin — this isn't your typical medieval tower house, but a Cromwellian-era fortification, a rare reminder of that turbulent period in Irish history. It's a quick but genuinely interesting stop if you want to get up close to a piece of post-conquest military architecture.
