The suspected site of a post medieval "Watch and Ward" lookout position.  The Hill for the Day Watch for Santon parish was at Knockloghan, as mentioned in a document dating to 1627 in the Castle Rushen Papers.  The associated Port for the Night Watch was at 'Gren Vicke', now called Port Grenaugh (at SC 317704).  An annotated 6 inch map shows 'Watch Hill' recorded by W. Cubbon at NGR SC 32737344, some 500 metres from Knock-y-Laughan farmhouse.


The early 17th century manuscript in the Castle Rushen Papers records, on a parish-by-parish basis, an arrangement whereby a coastal watch was kept for potentially unfriendly shipping.  It has been suggested by BRS Megaw (director of the Manx Museum 1940-57) that this system of 'Watch and Ward' had its origins in Norse times (1941), whilst more recently Johnson (2002) has proposed that promontory forts reoccupied during the medieval period formed part of the system.
