The aim of the project is to create a timeline including items from different countries. Each participant will study with his pupils the historical traces left in their region. We will search, and maybe visit historical monuments or museums and send to the others participants pictures and explanations. It can be an old church, a castle, a roman theater... It can also be an object found in the region, like a painting, a mosaic, a fossile... With all that, we will create a timeline, and students will be aware of some historical events which are not in their history books.
