Österreichische Gesellschaft für Festungsforschung



The Austrian Society for Fortification Research (Österreichische Gesellschaft für Festungsforschung – OeGF) was established to create a coherent scientific documentation about the Habsburgs’ monarchy fortification system between 1815 and 1918.

Covering the territory of 12 successor nations, this variety is also reflected by its members, who are specialising in certain regions and construction periods.

Another aim of the society is the usage of our research results for conservation/utilisation projects involving Austrian fortifications. The projects are supported on a professional level with the specialised know how of the OeGF.

Aside of this, our main instrument of communication is the OeGF website, where research results are presented in a very condensed way. Additionally our members are also involved in giving lectures or publishing books in order to increase the public awareness about Austro-Hungarian fortifications.

The Deutsche Gesellschaft für Festungsforschung (DGF)

Activities and Objectives

Fortifications, 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.

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





Malta (candidate member; see below)

Luxembourg was once called Gibraltar of the North and the enhancement of military heritage began right after the dismantling of large parts of the fortress which was decided at the London conference in 1867. The society “Frënn vun der Festungsgeschicht Lëtzebuerg a.s.b.l.” (FFGL) was founded in 1992 as a result of public involvement in saving the „Fort Thüngen“ from its planned integration in a new museum for modern art, as this would have meant a profound transformation of its historical value. The FFGL has also been successful in claiming the creation of a documentation centre focused on the topic of the fortifications in the “Grande Région” and more specifically the fortress of Luxembourg city.

The FFGL is active in the protection and conservation of the fortress of Luxembourg which has been a UNESCO World Heritage site since 1994. 

Among other activities, the society organises guided tours to those parts of the casemates that normally remain closed to the public. It also publishes a newsletter, brochures and books

Netherlands, The

Stichting Menno van Coehoorn (MvC)

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.

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.

The International Fortress Council and EFFORTS are partner orgsanisations

European Federation of Fortified Sites (EFFORTS) is the European network for fortified cities, forts and defence lines. EFFORTS members are cities, regions and knowledge institutions that aspire to European connection, knowledge exchange and EU funding opportunities. For the latter, EFFORTS has put into place the European Funding Professionals Network (EFPN) that concentrates on these European funding possibilities.


Working with representatives from all European countries, EFFORTS:

  • establishes a permanent European network of fortified heritage sites
  • sets up practical partnerships between scientific experts, policy makers, enterprises and practitioners in order to allocate means for innovative development of sites
  • provides an international exchange of information and research and expertise on innovative (re)use of fortified heritage
  • recognizes the tangible and intangible values and social and economic significance of fortified heritage
  • supports members in the development of fortification heritage
  • understands and promotes the regeneration and redevelopment of fortified sites and their surrounding urban and rural landscape
  • promotes accessibility for citizens and meaningful sustainable reuse of fortified heritage
  • highlights and raises the profile of fortified heritage, such as walled towns, fortresses and defensive lines




Fondazzjoni Wirt Artna, the Malta Heritage Trust,  is a voluntary non-governmental organisation active in the field of heritage preservation. One of its principal objectives is to create awareness to encourage the better understanding and preservation of the cultural heritage of the Maltese islands. For this reason, over the years, FWA undertook the rehabilitation and restoration of various cultural properties.

Today FWA looks after several historic buildings and sites in Malta. These properties span 7,000 years of Maltese history, from pre-history to the 20th century. These range from a megalithic temple at Kordin to a great baroque gate once serving as the main entrance into the imposing 7km long Cottonera bastioned ramparts; and from a Victorian fort armed with the world’s largest cannon to 20th century concrete defences.

Most of the cultural properties which FWA holds in trust, are made accessible to the public. In line with its objectives, FWA seeks to provide the visiting public with the highest form of interpretation that will enable a better understanding and appreciation of our cultural heritage. For this reason FWA also undertakes to build and maintain cultural collections with which to establish museums.
