More than £100,000 has been pledged to help bring buildings at Leicester Castle into permanent use.
Both the city and county councils have agreed to fund an in-depth study to see how it can be restored and adapted.
The only buildings that remain are the Great Hall, John O'Gaunt's cellar and the mound where the original castle would have stood.

An art gallery, museum and lecture theatre are a few of the ideas being considered for the site.
The Great Hall was used as the city's courts until 1980 but has stood empty for a number of years.
Andy Connelly from Leicester City Council said: "First of all there has to be a conservation statement which tells us what changes can and cannot make to the buildings.
"After that comes the feasibility study into possible future uses.
He added: "These are attractive buildings in an attractive part of Leicester and it is a waste not to have them used by the public."
