Svirlag, SvirLAG (Svirskiy Lager' – Svir Concentration-Camp, Russian: Свирлаг, also Свирьлаг / СвирЛАГ – Свирский концентрационно трудовой лагерь) was a Soviet forced labour camp run by NKVD's GULAG Directorate. It was located on the river Svir (hence the name Svirskiy in Russian) in the forests by the town Lodeynoye Pole, 244 km north-east of Saint Petersburg, in Leningrad oblast, Vepsland – the land of the Vepses, operated in the 1930s (Joseph Stalin's time) and onwards. SvirLAG concentration camp was supplier of wood to Moscow and Saint Petersburg.

The camp was established on November 17, 1931.^[1]

The number of those who died or were killed in Svirlag in 1930s (the times of the most numerous and heavy executions that took place in SvirLAG seem to be 1931–1937^{[citation needed]}) is measured in thousands of victims. In 1935, 36.500 inmates were kept in this camp.

The camp was located in the medieval buildings of what was formerly the Alexander-Svirsky Monastery. Bolsheviks closed and vandalized the monastery in 1918 (it finally ceased in 1925). The holy relics were removed, monks partly executed and partly expelled. The chief of the monastery archimandrite Evgeniy Trofimov was executed on October 23, 1918 along with 5 monks behind the monastery walls. The monastery buildings were turned into prisons, barracks, and mental asylum. On September 22, 1998 Ministry of Culture of Russia and Russian Ministry of State Property signed decree about delivery of monastery back to Saint Petersburg parish of Russian Orthodox Church.

"The situation review" of GULAG for October 1935 presents the average composition of the camp population as for October 1934 – 694,100 persons, as for October 1935 – 828,800 persons and of these 36,500 were concentrated in SvirLAG – 6th by size along with Bamlag (the biggest with 190,300 inmates in Svobodnyi, Amur Oblast), Dmitlag (193,300 inmates), Volgolag on Volga, Belbaltlag (82,000 inmates) and Ukhtpechlag in Ukhta, Temlag (21,100 inmates), Dallag (70,200 inmates), Siblag (Siberian concentration camp 74,600 inmates), Sazlag, Karlag (34,100 inmates), Prorvlag, Sarlag, Vetlag, Sevvostlag (47,700 inmates), Vaygach, Norilsklag in Norilsk.

Political and church convicts were kept there. Only 1 of 4 was a criminal.

The administration of the camp was based in Svirstroy (Svir Construction Directorate) on the Svir River. The convicted inmates worked in mines extracting mica, stone and clay.
