EFFORTS stands for the European Federation of Fortified Sites and is the European network organisation for the collaboration of almost 200 of Europe’s forts, fortified cities and regions in 23 EU countries. EFFORTS’ aim is to enhance structural European cooperation and coordination, to share expertise, to promote personal cooperation and to put fortified heritage on the agenda as a permanent link with our common European history. This in order to make a sustainable contribution to Europe’s economic, energy, spatial development and social challenges.
