An European cultural route is a themed route of cultural values or elements of cultural heritage that assigns a key role to cultural attractions of any international field in Europe. Each cultural route is specific in its own way and it differs from others by its theme, the length of the journey and the way in which the same ends (by car, foot, bike, hiking, etc.). The paper sets out the principles and aims which each route must satisfy in order the project could be realized, but as a crucial component, without which the European cultural routes can not exist, is an international collaboration which consists of professional teams and motivated stakeholders. In the paper are listed all the European Cultural Routes of the Council of Europe as examples of diverse and successful projects. In addition, above mentioned chapters are particularly emphasizing the importance of fortified defense systems across Europe which shares a common value that could lead to creating a new project of the European Cultural Routes of fortification architecture. Some of these defense systems are in very good condition thanks to the adequate and continuous use, while others are completely unknown at the local level. The main issues are the devastation of their architecture and inadequate use which is a result of nescience and neglect. Through my own opinion it was said to be that the ideal solution to above mentioned problems is education of the local population about the fortification resources in Europe through the organization of panels, seminars and various workshops. Thus, this paper ends with creating a possible cultural route through the past of the greatest treasures from the former Austrian-Hungarian Empire.
