One of the challenges facing multicultural urban communities – and one of the ways of nurturing co-existence – is motivating people from different backgrounds to learn more about each other’s history and culture, thus facilitating empathy and tolerance. In the same 1.5-mile stretch of open public space (Rose Kennedy Greenway) I spotted at least four different memorials and tributes to Boston’s diverse communities: the Tiananmen Square Massacre, the Irish community, the Armenian Genocide, not to mention an entire footpath dedicated to personalised stories of immigrants reaching Boston to be reunited with their families.
