Built in the 17th century, Castle Caldwell was part of the Ulster Plantation, a province of Ireland colonised by British settles throughout King James I era. The castle had a number of inhabitants after that and fell into ruin towards the 1800s.
Although access to the castle is now forbidden due to its dangerous state of repair, the surrounding park and forest can be explored freely. Keep your eyes peeled for the ruined chapel and overgrown graveyard.
