Tiger Cage

The notorious cells dubbed "tiger cages" were built in 1940 by the French to incarcerate nearly 2000 political prisoners; the USA continued using them in the 1960s and 1970s. There are 120 chambers with ceiling bars, where guards could poke at prisoners like tigers in a Victorian-era zoo. Prisoners were beaten with sticks from above and sprinkled with quicklime and water (which burnt their skin and caused blindness).
