Historic landmarks on the Lancashire skylines will soon have some new contemporaries - including a 25m "flying saucer" and a hillside atom.
The Halo has been dubbed the "flying saucer" by locals
The likes of Pendle Hill and Darwen Tower will stand alongside six new "21st century landmarks" created by architects for East Lancashire.
The four-year Panopticons project already has three definite landmarks - with three more planned.
The designs for second phase went on display for the first time on Tuesday.
Residents can have their say on the sculptures planned for Crown Point at Burnley, Peel Park in Accrington and Kemple End in the Ribble Valley.
They include a wind tower, a stone viewing wall, a 12m mast, the Fold lookout, a steel windbreaker, a design of 24 acrylic tubes, a wind tower and a "singing, ringing" metal tree.
The Singing Ringing Tree is shortlisted for Burnley
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 project is part of a wider parks' initiative by the East Lancashire Partnership and is partly funded by the North West Development Agency (NWDA)
All the structures - which are all shelters, viewing platforms or beacons - will be built by 2007 with some construction starting this Spring.
The Halo - the "flying saucer" - is to be installed on the hills of Haslingden in Rossendale.
It a 25m-diameter, circular steel structure, raised off the ground on a tripod, housing a solar array, self-powered cameras and lighting. The structure is clad in white photo-reflective material to ensure that it can be seen from miles around.
The Mirrored Atom will be installed in Wycoller Country Park in Pendle and Colourfields is a colourful lookout planned for Corporation Park, Blackburn.
The three designs for Burnley will be on show from a week at the library, the town hall and Towneley Hall.
Residents and visitors can see the Ribble Valley designs at Longridge Library, the council offices and Whalley library.
The Hyndburn sculptures will be on show at Accrington library, Accrington and Rossendale College, the town hall, Asda in Accrington, Huncoat primary school and Hyndburn sports centre.

Ian Whittaker, NWDA area manager for Lancashire, said, "The towns of East Lancashire sit in a pretty impressive landscape, but one which I think we sometimes take for granted.
"The Panopticons project will provide six striking and unique additions to this landscape.
"Such public art, incorporating high quality design in stunning settings, is a very important factor in showcasing the area as a great place for business to invest in and for people to live, work and visit."
