Casa de la Moneda - Potosí (Bolivia)

This is the old Spanish mint where the silver from the mines of Potosí was transformed into coins.

The original minting machines are preserved in a near-perfect state. The oldest machines were made of huge wooden gears and powered by slaves or animals (depending on availability). Later they used steam-powered machines, but luckily they kept the old machines untouched (just in case!). This huge building is now a national museum.
