The Middle of the World. The equator is supposed to run through here. Actually, there are 3 middles of the world. The one shown here was calculated by French scientists in the 19th or 20th century. This is where the big tourist site is, which includes a museum and some cafes. A second middle of the world was calculated, and its location marked, by a pre- Inca Indian civilization. The last middle of the world is the real middle of the world where the equator runs through, as calculated by modern GPS technology. In fact, between the pre-Inca and French middles of the world, the pre-Inca one was actually closer to the real one.
