What is "panopticons"

n. (plural of panopticon English)

'Panopticons' is an arts and regeneration project of the East Lancashire Environmental Arts Network managed by Mid Pennine Arts. It involved the construction of series of 21st-century landmarks, or Panopticons (structures providing a comprehensive view), across East Lancashire, England, as symbols of the renaissance of the area. Four large-scale sculptures were commissioned, designed and constructed over a six-year period for the districts of Blackburn, Burnley. The Halo in Haslingden (Rossendale) was the last sculpture in the series to be erected, in 2007.
