Ring of Castlehill is a Iron Age fort situated 380 metres south-west of Summer Byres in Caithness, Scotland. The monument is protected by Historic Environment Scotland under reference SM576. The fort occupies ground underlain by Middle Old Red Sandstone, a mixed geology of conglomerate, sandstone, siltstone and mudstone laid down during the Middle Devonian period, which provided stone suitable for construction of defensive works.
Iron Age forts of this type typically date between the 8th and 1st centuries BC and served as defensive settlements for local communities. They were commonly positioned on elevated or naturally defensive ground, with earthwork or stone ramparts enclosing domestic and storage structures. The fort at Castlehill represents an important example of Iron Age settlement strategy in the far north of mainland Scotland.
The monument's survival in the Caithness landscape reflects the archaeological significance of this region during the Iron Age, when such fortified sites were characteristic of settlement patterns across northern Britain. The fort's location relative to Summer Byres and its protection under national designation ensure its preservation as evidence of Iron Age occupation and social organisation in the far north.
