A judging panel is due to announce the winning design for a landmark sculpture on the Scotland-England border.
Three international contenders have made it to the final stage of the selection process for the Border Crossing project at Gretna.
The proposed structures range in height from 50m (164ft) to 100m (328ft).
Designer Cecil Balmond, American artist Ned Kahn and Chris Wilkinson, of Wilkinson Eyre Architects, are in the running for the project.
Judges met last month to select the winning design for the scheme - entitled the Great Unknown - but delayed making an announcement of their verdict.

Project manager Carol Hogarth said she believed all three options said "something important about Dumfries and Galloway and Scotland".
The winner of the project is to be announced at a special presentation in Gretna.
Sri Lanka-born Mr Balmond's works include the Arcelor Mittal Orbit tower, the UK's largest public art sculpture, designed in collaboration with Anish Kapoor for London 2012.
Environmental artist Mr Kahn has collaborated with architects and designers on a number of art projects all over the world.
London-based Wilkinson Eyre Architects enjoyed back-to-back success in the RIBA Stirling Prize for Architecture for the Magna Project in 2001 and the Gateshead Millennium Bridge in 2002.
