History

    Roller coasters have been around a surprisingly long time dating back to the 17th century. The first recorded roller coasters were in Russia and were called the "Russian mountains" (ironically). They were tall ice chutes constructed using frozen water and boards for support. It is believed that they were commissioned by Russia's Cathrine the Great in the Gardens of Oranienbaum in St. Petersburg in the year 1784. However, some say that that the french built the first ride in 1817 which featured wheeled cars that securely locked into tracks to keep it from flying off during high speeds.

man named La Marcus Adna Thompson Designed a gravity switchback railway that opened on coney island in Brooklyn, New York in 1884. How it worked is passengers would climb to the top of the ride, get in the cart and ride it to the other side where it switched tracks to return to the beginning. finding this to be quite inefficient Philip Hinkle introduced a full circuit roller coaster where the rider didn't need to leave the cart during the ride. Seeing this as a competition LaMarcus patented a design that included dark
tunnels and with that hired Fredrick Ingersoll's construction company to build them across the us during the first couple decades of the 20th century.
