Heritage is a messy concept ill-defined, heterogeneous, changeable, chauvinist – and sometimes absurd. In a TV programmer's words, just as ‘lifestyle has replaced life, heritage is replacing history'. Rather than ‘history’, Philadelphia's tourist boss now ‘talk[s] about heritage – it sounds more lively’. It is also more equivocal; as Walter Benjamin put it, every cultural treasure that is a ‘document of civilization is at the same time a document of barbarism’. Yet for all its ambiguity, ‘the idea of “Heritage” [is] one of the most powerful imaginative complexes of our time’.
