Atlas Obscura published a feature on the Tarrafal concentration camp in Chão Bom, Cabo Verde. The camp opened in 1936 under Salazar's dictatorship, when about 150 prisoners arrived from Lisbon, including communists, anarchists, trade unionists and sailors who had mutinied. The site was chosen deliberately because it was isolated, hot, short of clean water and plagued by malaria. Prisoners called it the Camp of Slow Death, and more than 30 Portuguese inmates died there, among them Bento Gonçalves, secretary-general of the Portuguese Communist Party.
