There are five pyramids which have been named the Pyramid of the Sun, the Pyramid of the Moon, the Pyramid of the Dragon, the Pyramid of the Earth, and the Pyramid of Love.
Here is an overview of the Visoko valley with the location of the pyramids.
The pyramid of the Sun is the talest one and it is estimated 722 feet (220 m) high, which would make it a lot taller than the Cheops pyramid in Egypt (147 meters).
