What is the connection between ‘Russian Mountains’ and the roller coaster?
Answer: ‘Russian Mountains’ was the name given to the precursor of the roller coaster. First originating in Russia in the seventeenth century, they were winter sleds attached to specially constructed mountains of ice, reaching up to 80 feet in height. They became hugely popular with the Russian upper class.
