After a short description of the church - architectural and structural - the author expresses his opinion about the causes of the damages evident on the church in 1984 when the study was carried out by: Anna Skaltsioti (Arch.) El.S. Menagias and N.Alevras (Civ.Eng.). Following that he presents the principles followed in the restoration of the building, the assumptions made, and the structural model used on the computer and describes in short the works carried out. He separates the various phases in order to underline the need for the careful study and restoration of old buildings from the point of view out only of their structural adequacy but also of their architectural and functional aspects.
