An old safe box (from 1780) with hidden locks

A safe box built in France in 1780-1810 and has three hidden locks disclosed with specific combinations.

It is amazing to see this technology used in France more than 200 years ago.

Given the beautiful castles built in France several hundred years ago, it was expected that the safes where they hid their money, jewelry and valuables would be very safe and with very complex locks.
