Fortress Study Group (FSG)


The Fortress Study Group is an international society concerned with the study of all aspects of military architecture and fortifications and their armaments, especially works constructed to mount and resist artillery.The Group was formed in 1975 to provide an opportunity for those interested in fortifications and military architecture to meet, get to know one another and publish their work. Since then the membership has grown to around 600, representing over 30 countries worldwide. They include professional architects and historians, retired or serving members of the armed forces as well as professional institutions and those with a casual but enthusiastic interest.The FSG actively encourages the research, study and recording of fortifications of all periods and publishes FORT, an annual journal, which contains articles about the theory, development, practice, conservation, adaptation and reuse of fortifications and military architecture. The group also publishes Casemate, a well-established magazine which appears three times a year. Every year the FSG organises a Conference Weekend in the UK, which includes trips to local sites of interest to the group and lectures on aspects of fortification. There is an annual Members Day with presentations from members, and a Study Day visit to a site of special interest. Each year a Study Tour examines the fortifications of other countries. Countries visited include Belgium, Bermuda, the Czech Republic, France, Gibraltar, Italy, Malta, the Netherlands, Poland, Portugal, Rhodes, and Slovenia. Members have been actively involved the restoration of fortifications and were keenly involved with the Defence of Britain Project, taking a leading part in the recording of WW I&II sites. Every 2 years a symposium entitled ‘Fortifications at Risk’ explores ideas on how the derelict fortifications of the British Isles can be protected and preserved. The group actively co-operates with other national and international societies with similar interests in other countries throughout the world. It is a member of the International Castles Institute (IBI) and a founding member of the International Fortress Council (IFC). For further information about FSG see

Stichting Menno van Coehoorn (MvC)

www.coehoorn.nl The Stichting Menno van Coehoorn is a national all-volunteer organization that promotes, since its founding in 1932, the conservation and protection of historical defence works, like walls, fortresses, casemates, defensive positions and defence lines. The Netherlands are in the lucky possession of a number of intact fortified cities, for example Naarden and Willemstad. Thanks to the Stichting Menno van Coehoorn these cities are kept in their original form. Aside from these spectacular monuments there are, all over the country, many other old military objects. They often are of (cultural-) historical and/or architectural value, as well as examples of town-building and landscaping. On many of these obsolete military installations – because of a long period of isolation – beautiful flora and fauna have developed. Fortifications of Dutch origin can also be found in many foreign countries. The Stichting Menno van Coehoorn also promotes the conservation and protection of those.

Frënn vun der Festungsgeschicht Lëtzebuerg a.s.b.l. (FFGL)


The Frënn vun der Festungsgeschicht Lëtzebuerg a.s.b.l. (FFGL) was founded in 1992. The background for the founding of the FFGL was the plan to build a Museum for modern art at Fortress Thüngen, and hence the perishing of a great part of the historical fortress.

The FFGL is active in the protection and conservation of many fortresses, like Fortress Lambert and ‘Festung Lëtzeburg”(Luxembourg). The organization organises frequently guided tours to parts of the casemates that normally remain closed to the public.

Deutsche Gesellschaft für Festungsforschung (DGF)


The Deutsche Gesellschaft für Festungsforschung (DGF)

Activities and ObjectivesFortifications, fortresses and forts are an important part of our cultural heritage. In recent years, the interest in historic fortifications has increased, and they have become generally accepted as valuable evidence of times past. This trend is also furthered by modern development concepts.The scientific research and transfer of knowledge not only include architectural history, but also economic as well as social history.Over the last decades, the DGF has taken an active part in this process by:

  • an annual specialist conference in one of the associated fortified towns,
  • study trips to locations in Germany as well as in foreign countries
  • the collection of literature, plans, maps and architectural drawings in our own archive in Juelich
  • advisory services to associations and municipalities with regard to the scientific study, conservation and restoration as well as utilisation of fortifications.

Publication Series

Festungsjournal (Journal of Fortification and Military Architecture)

This journal is published several times a year and contains information on recent developments and announcements relating to the association as well as essays/scientific articles, travel accounts, reports on study trips and reviews.
