Carrickfergus Castle stands proudly on the shores of Belfast Lough, its stone walls bearing witness to centuries of history. Among its many tales of woe and tragedy is that of a soldier known affectionately as Buttoncap, named for the large button on his headdress. This spooky soldier is said to haunt a small area near an old well within the castle grounds. Some claim he can be found in the well itself, a fittingly eerie location for a ghost with a tragic past.

The story goes that Buttoncap's life ended in a most unjust manner - he was executed after being falsely accused of an affair with his commanding officer's wife. This tale of betrayal and miscarriage of justice has led to the soldier's restless spirit roaming the castle grounds. While details of his haunting are scarce, the atmosphere of Carrickfergus Castle, with its rich history of sieges and battles, provides a chilling backdrop for Buttoncap's ghostly appearances.
