Cllr Seán Neeson said: “The HMS Caroline was decommissioned at the end of March and there is a great deal of uncertainty about her future.
“She is a major historic ship and is the last remaining remaining survivor from the battle of Jutland. She has played a major role in the maritime heritage not only of Belfast but the whole of Northern Ireland.
“HMS Caroline is a member of the core collection of national historic ships along with the Nomadic and the Result. Unless people in Northern Ireland make a major effort to keep Caroline in Belfast I believe that she could be moved somewhere else in the UK, and that would be a tragic loss as regards our maritime heritage and tourism industry.”
