It is just a coincidence that I am reading the book Gulag by Anne Applebaum while we are learning all the gruesome details of what happened in that prison in Baghdad. As I am very interested in photography I went online to look for photographic records of the Gulag. There’s a fairly large collection of images at the The Andrei Sakharov Archives and Human Rights Center. I also found a photo story about the Solovetski Islands - one of the first Gulag camps. Looks all very nice and scenic. What they don’t tell you on that website is that most of those buildings were prisons/camps of the worst sort - incl. the monastery. You can find lots of details about that in Anne Applebaum’s book. If you’re interested in more information this page has tons of good links to all kinds of materials.
