Cultural heritage fortress monuments
All European regions have a rich heritage of fortified monuments and defence landscapes. This unique cultural heritage of „architectura militaris“ represents the special identity and attractiveness of Europe. Fortified towns and citadels, fortified palaces and castles, fortified sacred buildings, large fortresses and lines of defence tell of European history, of empires and dynasties. Representative of the important cultural heritage of the old continent, some fortresses are part of the UNESCO World Heritage.
As cultural sites for art, tourism, leisure, architecture and history, fortified monuments today offer a high potential for valorisation with economic effects for cities and regions. Mobilising this tourism and economic potential is part of ECCOFORT's work.
It is based on intensive ECCOFORT research into the identification, localisation and typification of the cultural heritage of fortified monuments from a touristic perspective. The resulting unique map series on the inventory and structure of the European cultural heritage of fortified monuments is one result.
Distribution in Europe
Under the direction of ECCOFORT e.V., the surprisingly high density and distribution of fortress architecture in Europe is being researched. The period under consideration is the epochs from the introduction of firearms to the founding of the European Union. For the Central European region ECCOFORT e.V. created an overview map of the cultural heritage of fortress monuments for the first time in 2006, which is constantly being updated.

Typing
The „architectura miltaris“ refers to the ancient art of building to protect people, their goods and their living space, an extraordinary cultural heritage from several millennia of European history.
Irrespective of any scientific, architectural or historical categorisation, ECCOFORT adopts a Catchy standardisation tailored to the tourism market into the following epochs.
