Since 1977, Camilo Jose Vergara has been using photography to document the the transformation of urban landscapes in America. He describes his approach as interdisciplinary, using techniques from fields that include sociology, architecture, photography, urban planning, history and anthropology. Vergara has focused upon the gradual erosion of urban neighborhoods through neglect and abandonment, often photographing the same structures repeatedly over decades in order to capture this process of of urban decay. The photography presented here is from Vergara’s project entitled Invincible Cities.
