The possible site of a day watch beacon at the feature now named Cronk ny Arrey Laa. 'Blew Hill', Kirk Bride parish, is mentioned in the Castle Rushen Papers in a document dated 1627, where it is listed as a Hill for the Day Watch (Watch and Ward) although it is unknown in the parish and has not been traced in any early records. 


William Cubbon stated that the beacon must have been near Port Cranstal, the place of the Night Watch. The highest hill on the Bride coast is Cronk ny Irrey llaa (shown as Cronk ny Arrey Laa on the Ordnance Survey 1:10560 map of 1957), which is Gaelic for 'The Watch Hill', and Cubbon suggested this as the location of the Hill for the Day Watch. The majority of the Watch and Ward posts may well have been maintained on the same sites since the Middle Ages
