Just over a century ago, in the autumn of 1912, Thessaloniki and the rest of northern Greece entered a new historical phase through their incorporation into the rest of Greece. In 2012 the Archaeological Museum of Thessaloniki decided not only to participate in the events of this anniversary taking place in the city, but also to comment on the historical context of that era and initiate a public discussion, with the belief that a museum produces knowledge associated with collective memory (Gazi 2010, 350–357). It does this either by reinforcing existing memories or by providing new data or new readings of data, in a way that the messages from the past can become evident and useful in the present. The exchange of data between the present and the past has been described as bidirectional communication: questions about the past acquire meaning from their relevance to present interests and, at the same time, the answers given to those questions are made meaningful by the predominant concepts of the historical present (Liakos 2007, 120).
