The ruined remains of the Great North Laxey mines represent the site of a significant mining complex. The features are shown on the 1870 1:2500 scale Ordnance Survey map and include a shaft (SC42778890), two adits (SC42778892, SC42778886) a wheelcase (SC42848894) and powder house (SC42708898, possibly superseded – another one now stands at SC42718899). Other buildings of unknown purpose are shown, as well as washing floors and ‘deads’ or waste heaps.  The mine was served by a system of pumping rods running from waterwheels both overground on pillars and underground via conduits. Leats brought water from the surrounding hillsides to power the wheels.
