In Greece, there are around 16 pyramids. Though some may be natural pyramidal hills, others—like the Hellinikon pyramid near the village of Argolis—are clearly man-made structures. Intriguingly, one thermo-luminescence test by the Academy of Athens has dated the structure to 2720 BC, contemporaneous with the Egyptian pyramid age. Though pyramidal in shape, the Greek structures do not enthral like the Egyptian pyramids, which dwarf them in size.
The list of man-made pyramids (approved by archaeological features):
Pyramid of Hellinikon
Pyramid of Kampia – New Epidaurus
Egyptian Pyramid – Ancient Epidaurus
Pyramid of Ligourio – Asclepium (Ligourio)
Pyramid Dalamanara – Nafplion
2 Pyramids of Fichthia – Mycene
Pyramid of Neapolis
Pyramid of Hellinikon
Situated on the Peloponnes peninsular, 8.4 km Southwest of Argos and 3 km northeast of Kefalari. Its purpose is unknown, probably astronomical use as an observatory.
The Ligourion pyramid is found in north-western Peloponnese, near the village of Ligourion, at the base of Mount Arachnaeum, not far from the site of ancient Epidaurus. Unfortunately it has almost totally disappeared, with its blocks being a handy source of masonry for the locals. Some of the sandstone blocks were used to construct the walls of a nearby church. Originally, its base measured 14 by 12 metres and using the method of thermoluminescence it has been dated to roughly 2100 B.C.
This pyramid is located in the south of the Chania area, Crete, at an altitude of 290 m above sea level. It is roughly 8.5 metres high with a circumference of 29 metres. The interior of the cone has a chamber, carved out of the solid rock, of approximately 2.2 by 2.1 by 1.4 metres.
When excavations were made around the Greek pyramids in the early 1900s, pottery fragments from the 4th Century B.C. were found, and it was presumed that the pyramids were also constructed at that time; that is, about the time of Alexander the Great. Recent dating of crystals from internal surfaces of the limestone blocks using thermoluminescence puts the construction times back two millennia. The Hellinikon pyramid dates to 2730 B.C.; the Ligourio, to 2260 B.C. This means that the Greek pyramids were built in roughly the same time frame as the Egyptian pyramids.
