Carrickabraghy Castle is situated on the Isle of Doagh, around the corner from a fine view of Lagg Church on the opposite side of Trawbreaga bay. The building is shown in a map of 1690 as a tower house surrounded by an oval bawn wall with seven circular towers. Today, one circular tower survives against the keep. It is thought to date from the sixteenth century and was a castle of the O'Doherty’s, It is a very atmospheric place recently well conserved after local fundraising.
