The US prison at Guantánamo Bay opened 21 years ago this Wednesday. For 21 years, the extrajudicial detention facility has held a total of 779 men between eight known camps. In two decades, Guantánamo grew from a small, makeshift camp of chainlink cages into a maximum-security facility of cement bunker-like structures that costs close to $540m a year to operate.
