Strange Slope is a natural tourist attraction in China’s Liaoning Province, where a strange phenomenon causes things to roll uphill and prevents them from rolling downhill.
Located at the foot of Maoshan Mountain, near the city of Shenyang, the Strange Slope scenic area is considered one of the eight natural wonders of Liaoning Province. It was discovered in 1990, when, local stories say, a police officer stopped his car in the area and, taking his foot off the brake, noticed his vehicle slowly rolled uphill, all the way to the top. Word of the bizarre phenomenon spread like wildfire, and before long, people from all over the country, and even from abroad, were coming to see the gravity-defying slope in person. Authorities cleaned the place up, created separate lanes for bikes and cars, and Strange Slope became one of the most popular scenic areas in Liaoning.
