The first safes were actually built of simple materials, they were a simple wooden box with its door or lid and its lock; but due to the material it was very easy to destroy them and gain access to what they contained. Later, foil or brass began to be used, which began to shape the vaults that we now know, but which were still vulnerable to attacks by criminals.
Later, with the arrival of the industrial revolution and with capitalism on the rise, the need to protect many goods arose, then more reinforced steel plates began to be used until reaching the boxes that we know today, with systems that mix different materials; modern boxes, for example, are built with steel plates filled with concrete mixed with pieces of metal and a layer of steel pellets is also added, which makes them very difficult to drill.
The first patented safe was built in England in the 19th century, in that same century there were important advances in security which allowed the safes that we know today to be built. At present, many manufacturers use very sophisticated systems, in bank vaults, for example, a timer is used that although the combination is known, the system does not allow the opening of the vault until the scheduled time arrives; other systems use the biometric system that combined with the traditional dial provides highly secure access control. In short, there are many types of safes today, we can find very safe small safes to store valuables, security cabinets to store weapons, even high security vaults to store atomic weapons or dangerous chemicals.
