The Hill of Day Watch and Port for the Night Watch (Watch & Ward) for Ballaugh parish was located at 'Whetston Hill' according to a document within the Castle Rushen Papers dated to 1627.  The location of this hill is not known, but William Cubbon thought that it was on Ballakinnag (SC 340958) just below the old church of Ballaugh. The majority of the Watch and Ward posts may well have been maintained on the same site since the medieval period.
