<P> The first inversion in roller coaster history was part of the Centrifugal Railway of Paris , France , built in 1848 . It consisted of a 43 - foot ( 13 - meter ) sloping track leading into a nearly circular vertical loop 13 feet ( 3.9 m ) in diameter . During the early 1900s , many rides including vertical loops appeared around the world . These early loops had a major design flaw : the circular structure produced intense g - forces ( hereafter `` Gs '' ) . The Flip Flap Railway , designed by Lina Beecher and built in 1895 on Coney Island of Brooklyn , United States , had a 25 - foot circular loop at the end which though initially popular caused some discomfort in passenger 's necks , and the ride soon closed . Loop the Loop , another looping coaster , was built later in Coney Island as well . This time the loops were slightly oval - shaped rather than circular , though not clothoid in shape like modern loops . Although the ride was safe , it had a low capacity , loading four people every five minutes ( 48 people per hour , compared to 1800 riders per hour on Corkscrew , an early modern coaster that opened in 1976 ) , and was poorly received after the discomfort of the Flip Flap Railway . As their novelty wore off and their dangerous reputation spread , compounded with the developing Great Depression , the early looping coasters faded and disappeared . </P>
