Practices from across the world have passed the first stage in the Pennine Lancashire Squared competition.
There are six shortlists, each consisting of five teams, chosen to come up with concept designs for Burnley, Accrington, Blackburn, Bacup, Clitheroe and Nelson.
The competition, run by the Landscape Institute, was commissioned by regeneration agency Elevate and is the brainchild of Yvette Livesey and her late partner, music mogul Anthony H Wilson. They proposed the holding competition as a way of attracting talent to the area, raising its profile and creating outstanding public spaces in each of the six towns.
In a judging day held last week, the 78 "expressions of interest" were whittled down to 26 landscape architecture and architecture teams to compete.
