The Fortress Study Group endeavours to try and help preserve military architecture and contribute to academic learning.  Although we have only limited funds we endeavour to help in our own small way such as:

  • Publishing fortification research in FORT and Casemate which are distributed to academic libraries worldwide.
  • Grants to authors to help with their research and publications on subjects within our field of interest.
  • Small grants to organisations preserving and interpreting fortifications. 
  • Awards to fortification groups to acknowledge their good work in promoting and protecting a specific fort.
  • Providing expert advice to development proposals.

See also our Charitable Activity page for further information and our grant application form.
