The possible location of a medieval 'Watch and Ward' lookout. A document in the Castle Rushen Papers dated to 1627 mentions that the 'Hill for the Day Watch" in Rushen parish was at 'Bradoe', which is thought to refer to Bradda Hill.  The grid reference relates to the highest point on the hill, but there is no guarantee that this was the location at which the watch was kept.  A cairn of unknown date and purpose lies 55m to the east.


The corresponding 'Port for the Night Watch' for the parish was located at 'Port Yrne' (Port Erin).  


It is thought that most Watch and Ward posts were maintained on the same sites from medieval times into post-medieval times.
