President John Mahama says the Osu Castle will be opened to the public once he finishes moving out.He said the public will then have access to the colonial edifice, which they will also be allowed to photograph.The president was speaking at a short ceremony at the Flagstaff House Thursday to symbolize the relocation of the seat of government.He described the relocation as the closure of a chapter of Ghana’s history and the dawn of a new era.The Osu Castle, which some say symbolises Ghana’s triumph over imperialism, has been the seat of government for over five decades.Security officials have often prevented ordinary citizens from approaching or loitering around the structure and photographing it was similarly forbidden.But the president said Ghanaians will be able to visit the site and take photographs once the Castle is opened to the public.
