This star-shaped military fortress was constructed between 1677 and 1682, during the reign of King Charles II, to protect the town and harbour of Kinsale in County Cork. William Robinson, architect of the Royal Hospital in Kilmainham Dublin, and Superintendent of Fortifications, is credited with designing the fort. As one of the largest military forts in the country, Charles Fort has been associated with some of the most momentous events in Irish history. These include the Williamite War in 1690 and the Irish Civil War of 1922 - 23. Charles Fort remained garrisoned by the British army until 1922. Children must be accompanied by an adult at all times.
