The app contains information about all 20 monasteries in Mount Athos, as well as many of the hermits, as well as useful information for pilgrims such as behavior rules, telephone numbers of mountain huts, etc. Each monastery or hermitage has associated GPS coordinates, and the app indicates the distance to the location (in a straight line) as well as the weather. The information about the Holy Mountain of Athos in this application is the source of the homonymous work published in 2015 at the Evangelismos Publishing House. The application was created with the blessing of Jeruschim. tefan Nuescu from Chilia Buna Vestire, Lacu Hermitage, Holy Mount Athos. The information contained in this work as well as the development of this application required important human and material resources, so if you find any use in our effort, please donate any amount of money (the link is in the application).
