The aim of the project „Heritage for tomorrow – from understanding to enjoyment“ was to increase students´ interest in historical values left by our ancestors, to learn about the national cultural and natural heritage of their country as well as other European countries and to lead them to the findings that the true values are sustainable. Therefore we have to appreciate and keep them for other generations. We chose the period of the Roman Empire as the example of heritage sustainability as it left its marks in many European countries.The planned activities and project products became a part of the educational process and afterschool activities. The topic of the ancient Rome belongs to the curriculum of the school subject History, so the students prepared presentations, brochures, video, e-books about the life in the Roman Empire. They created the map of the Empire, the dictionary of Latin phrases, a quiz, 3D models of famous Roman sights, which were presented to other students. The learning/teaching process was enriched with learning-by-doing activities when students discussed with members of a historical group and learnt about the life of Roman army, its gear and armament, they could wear it and simulate gladiator fights. Another interesting activity was a discussion on Roman law led by an expert or senior students who presented the Roman Empire´s influence in this field as well.An important part of the project activities was visiting places and sights that belong to the national cultural and natural heritage and those which belong to the UNESCO World Heritage. We visited the places which are unique and reflect the national identity – open air and archeological museums.The students got familiar with the cultural heritage of their own country and during the learning/teaching/training activities in the partner countries they had opportunities to learn about their heritage and see the sights of the Roman Empire, which helped them to apply their theoretical knowledge to practice .The project products can be used in the educational process in the future for some school subjects – history, art and culture, English, IT as teaching aids and additional material as well as examples of students´ creativity, which could be a motivation for increasing students´ interest in the subject or the project topic itself.
