Pyramid of Ligourio

37.6169°N, 23.0308°E.

The Pyramid of Ligourio in the Argolid region of the Peloponnese, southern Greece — a small dressed-stone pyramid conventionally dated by mainstream Greek archaeology to the Classical or early Hellenistic period (approximately fourth or third century BCE). Original base approximately 13 metres per side; original height around 10 metres in a single sloping square structure built of polygonal limestone blocks fitted without mortar. Excavated in part by the Greek Archaeological Service in the early twentieth century. Like the more famous Hellenikon Pyramid 30 kilometres west, the Ligourio structure has been variously interpreted as a watchtower, a mortuary monument, a road-marker, or a fortified guard-post. The same disputed thermoluminescence dating campaign of the 1990s that produced controversial Bronze Age dates for Hellenikon also tested Ligourio with similar early results that mainstream Greek archaeology does not accept.

A second small dressed-stone pyramid in the Argolid landscape, sharing the same construction template as Hellenikon and the same unresolved questions about its date and function.
