The Holy Mountain of Athos is a self governing monastic republic on a peninsula in Northern Greece. Standing on the shores of the Aegean Sea is one of the twenty ruling monasteries that comprise the republic, that of St Panteleimon, known in Greek as the Rossikon. It's building, fully restored in recent years, can accommodate up to 5,000 men, reflecting the scale of the settlement at its apogee in the nineteenth century and prior to the Bolshevik revolution in Russia. Since the fall of the Soviet Union in 1991 it has experienced a strong revival and is now one of the most numerous of the twenty. 0But the vast buildings that can be seen today are really only a reflection of the history of the past two centuries. Much less well known is the fact that the history of a Russian presence on Athos goes back more than one thousand years. This is the first comprehensive account of this in the English language.
