Among its members are the late Prince Philip, Duke of Edinburgh and King Charles III, of the United Kingdom, who is the royal patron of the society.
[2] As a service to the monasteries and to pilgrims, the society clears and maintains the ancient footpaths of Mount Athos, with many of the stone-paved kalderimi paths dating back to the Byzantine era.
It also provides on its website detailed footpath descriptions with GPS tracks, and a regularly updated report on the condition of the paths.
FoMA member and cartographer, Peter Howorth of Christchurch, New Zealand, working with the society's footpath team, has recently published a new Pilgrim Map.
It also publishes A Pilgrim's Guide to Mount Athos in both printed and continuously updated digital forms.
