An Early Bronze Age flat axehead was exposed by marine erosion at Hango Hill in 1847. The Manx Liberal newspaper of 24th April reported, "An ancient bronze celt, found at Hango Hill, near Castletown, after the late incursion of the sea, has been presented by Mr John McGhie, brass founder, to J.R. Wallace, for the Cumberland Museum."


The axe was subsequently transferred, along with other Manx items in the Wallace Collection, to the Manx Museum. It is now part of the Manx National Heritage collections, accession no 1954-0794.


The prominence of Hango Hill itself suggests a potential origin as a prehistoric burial mound (see also PRN 0031); it has since been used as a Medieval burial mound, an execution site, as the foundation for a banquetting hall, and as a gun battery.
