The Panopticon Halo is 18m in diameter and constructed on a hill above Haslingden in the Rossendale Valley in Lancashire. The steel lattice halo structure is supported on a tripod 5m above the ground. The Halo is luminated by LED’s and looks like some UFO hovering and coming in to land and beam me up!!
More information is available and the many other interesting structures to see on the Visit Lancashire website.
