A planning application has been submitted for the £25m transformation of Armagh Gaol into a four star hotel.
Bath-based Trevor Osborne Property Group, which specialises in heritage projects, has worked on the application with Armagh District Council and The Prince's Regeneration Trust.
The planning bid would see the Grade B listed buildings, which famously housed Republican women prisoners during the Troubles, converted into 65-bed, four star hotel with a spa and conference facilities.
There would also be restaurants, shops, bars and an education and heritage centre on the site.
Lord Mayor of Armagh Sharon Haughey said: "As a luxury hotel, the Armagh Gaol site could not be better, looking across the city's famous Mall to the courthouse on the opposite side and surrounded by Georgian houses.
"We hope that work will commence in 2014 and that the expected two year development will create long-term employment opportunities and deliver skills training through apprenticeship programmes," she added.
