This is an old Stationary steam engine that was powering the Minting Machines.­

It is located in the Casa de la Moneda (Potosí, Bolivia), 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.­
