Williamson Tunnels, Liverpool - Boiler Room

sketchfab

My first test of photogrammetry, in the historic Williamson Tunnels in Liverpool. They were built circa 1810-1840 by a mysterious businessman, Joseph Williamson, who constructed a sprawling underground network of vaulted chambers and tunnels for unknown purposes. They’re now being explored and excvated by volunteer diggers (myself included!) and sections are open to the public for guided tours.
