                                        A spiral staricase leads from the Old Hall to the bedroom above, in which all the immediate Hunter family would have slept. In was in this room that Robert Caldwell  Hunter was born in 1799. In that year his parents commenced the building  of Hunterston House. 
                                        At the top of the  Pele tower is a garret and parapet, this is now reached by a spiral stone stairway. When the Castle was built there would have been a wooden ladder  for access. 
                                        Hunterston Castle  is unique in that it has its original roof beams with the carpenters marks  clearly visible. The roof beams are a excellent example of medieval carpentry, constructed with mortice and tenon joints secured with pegs. 
                                        The parapet is narrow  to assist with defence as the early Hunters used crossbows for defending  the Castle. The south wall has a machicolation to make defending the front door easier. The front door was on the first floor at this time in common  with other Castles of this time
