Соловецкие острова
Historically, the Solovetsky Islands were the location of the famous Russian Orthodox Solovetsky Monastery complex. It was a centre of economic activity with over three hundred monks, and also a forepost of Russian naval power in the North, repelling foreign attacks during the Time of Troubles, the Crimean War, and the Russian Civil War. In the autumn of 1922 the process of transitioning from a monastery to concentration camp began.
