Pupils from a primary school of Athens, a junior high school in Dijon and a special school of Athens visit monuments of cultural heritage of their cities, take photos, search for information, locate them on maps and create a collaborative digital tour map. They present important monuments of their cities to their fellow pupils from the corresponding countries and get aquanted with monuments of foreign countries using plaster copies of Iris, the mesenger of the gods in Ancient Greece, that they have created and painted themselves. Iris guides them to important monuments with the use of AI and the recorded voices of the pupils. Finaly they create 3D puzzles of iconic monuments of their cities. The pupils impressions about the project are presented in a wordcloud.
