What is the only place on earth that has a latitude and logitude of 0?

The only place on earth that has a latitude and longitude of 0 degrees is in the Gulf of Guinea of the Atlantic Ocean. It is the place where the equator having zero degree latitude intersects with the prime meridian having zero degree longitude. It does not have any special significance at all. This place is located about 670 miles west of the country Gabon and 380 miles south of the country Ghana. While the equator can be considered as having significance because the sun gets directly overhead during the months of March and September equinoxes but the prime meridian is just an imaginary line.
