As the families of victims of the September 11, 2001, attacks prepare to mark a fourth anniversary of the deadly day, plans for the World Trade Centre site remain mired in controversy.Looking at everything from a proposed Freedom Tower skyscraper to a cultural centre at the site, families are criticising the plans as irrelevant to the lives lost.‘‘There is something within the national psyche that recognises this spot as graveyard,’’ said Colleen Kelly, whose brother died in the towers. ‘‘A lot of the conflict is stemming from an internal reaction recognising that this is a sacred space.’’Plans called for a cultural centre to house an International Freedom Centre museum and an art gallery called The Drawing Centre.Victim’s relatives have complained that the cultural centre is inappropriate.However, Jeremy Soffin of the Regional Plan Association, a nonprofit think tank on planning and development issues, said just a small number of family members oppose the centre.‘‘A small minority of families who have always had concerns about the master plan are rallying behind this issue,’’ he said. ‘‘The whole site can’t be a memorial because this is a living, breathing part of the central business district.’’ —Reuters
