A hilly space planned for Hyndburn is being redesigned
"Public in Hyndburn agreed to the principal of the project but were uncomfortable with the designs," Gail Knight of the Panopticons project said on Thursday.
"The designer said he was using the initial designs to provoke debate and discussion. Now he is redeveloping the design and it will be radically different.
"He has done his research on the heritage of the town and the history - I think the new designs will be more in keeping with what the public is asking for," she said.
Work is due to begin on the three other landmarks - the 25-metre Halo, dubbed "the flying saucer" in Rossendale, Colourfields for Blackburn and the Atom for Pendle.
Panopticon means a structure which creates a panoramic view, setting down the aim of the project on some of the county's highest points.
Mid Pennine Arts is co-ordinating the Panopticons and the first three designs were created as part of a competition with the Royal Institute of British Architects.
The structures - which are all shelters, viewing platforms or beacons - will be built by 2007.
