Gloucestershire's Cotswold hills and the Severn Vale hold a dense record of Iron Age hillforts, Roman villas and medieval sheep farming, much of it only visible once you strip the landscape down to bare terrain.
This page covers Gloucestershire and its neighbouring unitary authorities — Bristol, Bath and North East Somerset, North Somerset, and South Gloucestershire — so you can explore LiDAR terrain across the wider area.
Cirencester was Roman Britain's second-largest town after London (Corinium Dobunnorum), and LiDAR across the surrounding Cotswold farmland still picks out its road network and the villa estates that grew up around it. Bath's Roman and Georgian layers sit on top of each other in a way that's hard to untangle on the ground; further out towards Bristol and the Severn shoreline, the terrain view is better suited to spotting medieval field boundaries and old quarrying than anything Roman.
