Safe-deposit boxes

The earliest banks stored the cash and valuables of their clients in armoured chests equipped with multiple locks, like the classic treasure chest seen in pirate movies. During the nineteenth century, the safe became popular: a fireproof cabinet made of steel, furnished with a key- or combination-lock, often seen in old-fashioned Westerns. Then, in the twentieth century, came the safe-deposit box: one key for the customer, one key for the bank. Together the boxes covered an entire wall in the bank's vault. Now they are part of two service counters in Circl.
