Greek pyramids, also known as the Pyramids of Argolis, refers to several structures located in the plain of Argolid, Greece. The best known of these is known as the Pyramid of Hellinikon. In the time of the geographer Pausanias it was considered to be a tomb. Twentieth century researchers have suggested other possible uses.
Writing in the 2nd century AD, Pausanias mentions two buildings resembling pyramids, one, twelve miles southwest of the still standing structure at Hellenikon a common tomb for soldiers who died in a legendary struggle for the throne of Argos and another which he was told was the tomb of Argives killed in a battle around 669/8 BC. Neither of these still survive and there is no evidence that they resembled Egyptian pyramids.
There are also at least two surviving pyramid-like structures still available to study, one at Hellenikon and the other at Ligourio/Ligurio, a village near the ancient theatre Epidaurus.
At the Southeastern edge of the plain of Argolid, near the springs of the Erasinos river (nowadays Kephalari) and on the main arterial road which in antiquity led from Argos to Tegea and the rest of Arcadia and Kynouria, there is a small structure extant known as the Pyramid of Hellenikon.
