Three ramparts, ditches and the memory of timber palisades mark the Iron Age stronghold on Castle Law’s slopes. South-west of Fairmilehead in the Pentland Hills, the scheduled fort looks out across the Forth and Lothian towards other major Iron Age places.
When occupied, the stronghold had three earthwork ramparts, ditches and timber palisades. It also held a souterrain (an underground stone-lined passage) for storing agricultural produce, making the site not just a lookout and defence work but part of a working farming landscape.
What follows is drawn from published sources, with each claim labelled by how firmly it is established.
History
In the Iron Age, Castle Law was occupied as a fortified stronghold on the slopes of the Pentland Hills. Its defences consisted of three earthwork ramparts, ditches and timber palisades.
The fort contained a souterrain used for storing agricultural produce. That underground storage points to the everyday economy behind the defences, where food security mattered alongside the site's visual command.
The fort commands views over the Forth and Lothian. Traprain Law and Berwick Law, both significant centres of power in the Iron Age, are visible from the site, tying Castle Law into a wider landscape of hilltop authority.
In 1932-33 V. Gordon Childe excavated at Castlelaw. His work focused on the rampart and showed that it had a clay and timber filling faced with stone.
The site is now maintained by Historic Environment Scotland as a scheduled monument. Access is free, but the pack notes that the hill is active sheep pasture and neighbours an army firing range, so visitors should keep dogs under control and avoid areas marked by red flags.
In 2017 AOC Archaeology began further excavations at Castle Law, listed in the pack among the external sources for the site.
