<< Objectives >>Visegradopedia is a multilingual online encyclopaedia that brings together in one place the most important knowledge material about the Visegrad countries. It is a shared knowledge base that can be used by schoolchildren aged 10-18 for their school studies, where they may find accurate, professionally credible information in one place. In addition to supporting learning, the encyclopaedia can also be used for general information on specific countries.<< Implementation >>The project shall produce a self-developed website and mobile application. At launch, at least 200 articles shall cover the most important facts about the history, economy, culture and science of the countries. The textual information in the articles is complemented by illustrations, animations and photographs. All articles are available in English, Hungarian, Polish, Czech and Slovak, so users can choose between the languages.<< Results >>The project shall enable a deeper understanding of each other's countries, and the discovery of similarities arising from their common past and history. Multilateral cooperation helps to build mutual trust based on credible knowledge and to overcome remaining prejudices.The countries presented in the encyclopaedia give student users a more nuanced, broader view of the countries than available in their textbooks.
