The group will consult with interested parties and evaluate viable options before bringing recommendations to the Policy and Finance Committee.
It will then take responsibility to progress the chosen option to fruition for the benefit of the Nunnery heritage site and the community.
The group consists of Alderney States chief executive Kath Jones, P&F chairman Bill Abel and Economic Development chairwoman Annie Burgess.
‘This is a superb opportunity for the island to be creative in its thinking around this unique asset,’ said Mr Abel.
‘We have a blank canvas that is open to input from anyone with a forward-looking proposition.’
The ABO, which operates a field centre and hostel at the Nunnery, is on three months’ notice following the States’ decision last week.
The heritage site is the best-preserved small Roman fort in Britain dating back to the 4th century AD and attracts numerous visitors with its historical displays and information room covering Roman, Tudor, Victorian and Second World War eras.
