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.

This fortified house is on Tully Point and built for Sir John Hume who occupied the house until 1641 when it was attacked by John Maguire and burned on Christmas Eve with all its inhabitants massacred. After that it was not lived in again. There is a visitors centre in a restored farmhouse that has an interesting exhibition telling a number of stories relating to the castle. To visit the castle be sure to step off the bike as it is on foot only!
