The Lion Salt Works is the last remnant of an industry stretching back two millennia and is a Scheduled Monument.
The pan houses and stove houses were greatly decayed through exposure to salt and subsidence and many were in an advanced state of collapse. Donald Insall carried out a feasibility study, prepared a Conservation Plan and developed innovative proposals for the reuse of the site, which were awarded £5 million HLF funding.
They were then appointed to provide architectural services for the restoration of the delicate industrial buildings and regenerating the site as a visitor attraction and salt museum. A new visitor centre was provided as part of the project.
