Jersey's government is looking for entrepreneurs to take over the bunker and tunnel complex at St Catherine.
Businesses are being invited to pitch viable ideas to open up the area to the wider public.
The site was once used or German forces and incorporated two heavy machine gun bunkers, shelters, anti-tank defences and a tunnel.
Events and Project Support Manager, Kim Gilbraith, says this is a unique opportunity to enhance a piece from the island's history.
“St Catherine's war tunnels hold a profound historical significance, serving as a lasting testament to the island's wartime past and offering an educational experience for visitors.
We would like to hear from experienced businesses with a passion for Jersey’s heritage and who are keen to contribute to the local economy by enhancing visitors’ experience of this beautiful location.
This is a chance to contribute to the local community and to the preservation of a valuable historic building."
Prospective leaseholders can express their interest by emailing jerseyharbours@ports.je.
