The city is by definition a living entity. It translates itself into a collectiveness of individuals who share and act on a material, social and cultural setting. Its history is one of dreams, achievements and loss. As such, it also bears a history of identity. To know the history of cities is to understand our own place in the contemporaneity. The past is always seen through the eyes of the present and can only be understood as such. On the occasion of the 261st anniversary of the 1755 earthquake in Lisbon, we invite scholars and experts in the fields of heritage studies, digital humanities, history, history of art and information technology to share and debate their experience and knowledge on digital heritage.
