Rivers of blood in Moscow: The Great Purge personified
Spatial distribution of executions in Stalin’s Moscow
Even though lump evidence of crimes committed by the Communist regime in Russia has been uncovered in the last two and a half decades all but none attention was paid to spatial analysis of executions in major cities.
The Memorial Society’s database of purges of Moscow residents in 1930s-50s enables me to map victims on a house-by-house level of detail.
Below is the map. Each dot is clickable and denotes at least one person, totaling 11170 people.
