Hango Hill, Historic execution site in Malew, Isle of Man.

Hango Hill is a historic site in Malew, Isle of Man, where 17th-century hall remains can be found near the coastal road between Castletown and Derbyhaven. The location offers views across Castletown Bay and is accessible via walking paths that link to other heritage sites in the area.

The site served as a burial ground during the Bronze Age, marked by the discovery of a bronze flat axe in the area. It later became a place of execution, a role reflected in its name and defining its later historical purpose.

The name comes from Old Norse 'hanga-haugr', meaning Gallows Hill, which reflects the site's role in historical executions. This designation remains part of how locals understand and speak about the place.

Hango Hill stands on the coast road between Castletown and Derbyhaven in Malew parish. The mound is a short walk from the roadside, and King William's College lies directly across the road. The summit holds only the eroded fragment of the 17th-century hall, so the ground is uneven underfoot.

The ruined structure on the summit is not a memorial: it is what remains of Mount Strange, a summerhouse about 10 m long built by the Earls of Derby after 1663. Coastal erosion has left roughly a third of it, and early drawings show battlements. The earls used it while organising horseracing on the dunes toward Langness, the first "Derby" races.
