Ancient place of execution. Here, Illiam Dhone, a National hero to Manx people, was shot on the 2nd of January 1663 for his part in the Manx rising of 1651. The ruins are those of a late 17th century summerhouse known as Mount Strange. It is also possibly a prehistoric burial site with an artificial mound. Its name comes from the Norse 'Hanga-Haugr', meaning Gallows Hill.
