Wikimedia Commons has media related to Gravity hills.
A gravity hill (also known as a gravity road) is a place where the layout of the surrounding land produces the optical illusion that a very slight downhill slope is in fact an uphill slope. Thus, a car left out of gear will appear to be rolling uphill. There are hundreds of known gravity hill locations around the world.
