Where was the first roller coaster set up?

The earliest roller coaster was the Russian winter sled ride, set up in specially constructed hills of ice around Petersburg. It was built in the 17th century. The slides were built to a height of 70 to 80 feet and consisted of a 50-degree drop duly reinforced by wooden supports. The first roller coaster per se was created in Paris in 1804 which was named ‘The Russian Mountains’.
