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.

A hall was built on the summit of Hango Hill by the earls of Derby in the years following the execution of William Christian in 1663. The hall was about 10m in length, but now only about a third survives following the erosion of the coastline. Early drawings show a building with battlements, and it has been referred to as a 'blockhouse'; it seems however only ever to have served as a banqueting hall and a summerhouse, and it was associated with horseracing organised by the Earls along the dunes to the east onto Langness - the first 'Derby' races.

An unknown number of burials were recorded in the eroding coastal face of the mound prior to the construction of the protective sea wall. Local tradition averred that these were the victims of executions, but it has been suggested that the site might have served as a medieval burial ground.

The name Hango Hill may have its origins in the Old Norse for 'hanging hill', implying that the site was used as a place of execution in the medieval period. Nevertheless, the site is most well-known as the place where William Christian was executed in 1663 for his part in surrendering the Royalist-held Island to Parliamentary forces in 1651.

A battery of four small cannon is recorded as present on Hango Hill in the later 17th century but had fallen into decay in the first half of the following century. It is difficult to see how these might have been accommodated on the present summit of the hill, especially as the banqueting hall was already present, and it may be that the open ground immediately to either side of the hill itself actually provided an emplacement for the battery.

The site of a promontory fort which was thought to be of possible early medieval or Viking origin. A later fort was said to have been built by Captain John Hanmer, a Governor of the Isle of Man, in 1575 and rebuilt in 1689. The site has been lost to coastal erosion in the 20th century.
