Saint Panteleimon Monastery (Greek: Μονή Αγίου Παντελεήμονος, romanized: Moní Agíou Panteleímonos, Russian: Монастырь Святого Пантелеймона), also known as Rossikon (Greek: Ρωσσικόν, romanized: Rossikón Russian: Россикон) or New Russik (Greek: Νέο Ρωσικό, romanized: Neo Rosiko, Russian: Новый Руссик, romanized: Novyy Russik), is one of the twenty Eastern Orthodox monasteries on Mount Athos, located on the southwestern side of the peninsula in Northern Greece.

[citation needed] The construction of the present monastery on a new site, closer to the seashore, was carried out during the first two decades of the nineteenth century, with the financial help of the ruler of Moldo-Wallachia, Skarlatos Kallimachos.

[2] The Monastery of St Panteleimon was repeatedly gutted by fires, most famously in 1307 (when Catalan mercenaries set it aflame) and in 1968.

Today, the monastery features the architecture of a small town, with buildings of various heights and many domes.

As a result, the number of Russian monks in the monastery and on Mount Athos generally, was reduced from several thousand in the 1900s to 13 in the early 1970s.

[2] Notable former monks of the monastery include Daniel Katounakiotis,[4] Silouan the Athonite, and Archimandrite Sophrony.
