The site of a possible late medieval to post medieval Watch and Ward beacon. The Carnane, which is now the heather-covered portion of Douglas Head, was a Hill for the Day Watch of Braddan parish as mentioned in Castle Rushen papers dating to 1627. A view of Douglas drawn by Daniel King circa 1650 marks the path to the Carnane as the way 'to the Beacon'. The Port for the Night Watch was at Douglas town.
