Halangy Down, Iron Age settlement ruins on St Mary's island, United Kingdom
Halangy Down comprises ruins of a settlement with multiple stone houses arranged across four narrow terraces down the slope. The dwellings feature thick walls, circular floor plans, and connected courtyards that formed the core of the village layout.
The settlement began in the Iron Age and continued to be inhabited and modified through the Roman period. Archaeological evidence shows habitation spanning from around 800 BC until approximately 100 AD.
The site shows how people adapted their homes to the sloping terrain over many generations. Visitors can observe how residents arranged their houses around shared courtyards and modified structures to fit the landscape.
The ruins are located about 1 mile north of Hugh Town and are reached via coastal footpaths through the surrounding terrain. Wear sturdy shoes as the site has steep slopes and the ground can be muddy or wet.
A standing granite stone marks the northwestern slope near earthworks built during the Civil War period. These fortifications with banks and ditches show the site was reused for military purposes centuries later.
