アイルランドのお城

Castles & Fortifications

Leinster's landscape is defined by defensive architecture spanning nearly a millennium. This collection includes the 12th-century Trim Castle, Ireland’s largest Anglo-Norman fortification, and the 13th-century Dublin Castle, a former seat of British rule. Visitors can explore well-preserved tower houses like Slade Castle, Gothic-revival mansions such as Charleville, and the extensive ruins of Kells Priory. From the Viking-era foundations of Reginald's Tower in Waterford to the expansive estates of Birr and Slane, these sites illustrate the transition from medieval strongholds to stately residences.
