Castle Greg

Castle Greg is a Roman fortlet with a rectangular design protected by two defensive ditches and a rampart on Camilty Hill. The structure covers roughly one acre and sits at a strategic location for monitoring routes across northern Britain.

The fortlet was built during the Roman occupation of northern Britain. Excavations in the 1850s uncovered fragments of glass, pottery, and pottery vessels that dated to this Roman period.

The fort demonstrates Roman military architecture and defense strategies of the occupation period. These small outposts were typical of how Rome controlled and monitored movement across northern Britain.

The site is accessible from the B7008 road, located a few miles southeast of West Calder. Visitors should wear sturdy footwear as this is an open-air archaeological site with uneven terrain.

The fort controlled a key east-west trade route between the Forth estuary and the Clyde Valley. This passage was vital for Roman logistics and communication across their northern frontier.
