La Mitad del Mundo (the middle of the world) is a small village administered by the prefecture of the province of Pichincha, north of Quito. It has since been determined, with the use of Global Positioning System technology, that the actual equator is some north of the monument area. Nearby is the Intiñan Solar Museum, which may be closer to the true equator. The Intiñan Solar Museum provides a demonstration which purports to show the Coriolis force causing a clockwise rotation of sink water a few meters south of the equator and a counterclockwise rotation a few meters north, but many scientific sources claim that this is implausible.
