Pyramid of Viglafia

36.5200°N, 23.0500°E.

The Pyramid of Viglafia at Cape Maleas in the southeastern Peloponnese, Greece — the southernmost of the documented Greek pyramids, conventionally dated by mainstream Greek archaeology to the late Classical or early Hellenistic period (approximately fourth or fifth century BCE). Original base approximately 10 metres per side; original height around 6 metres in a sloping square structure of dressed limestone blocks. The location at Cape Maleas places the structure on one of the most strategically important maritime headlands in the ancient Mediterranean — the cape rounded by all shipping moving between the Aegean and the western Mediterranean. The pyramid's interpretation as a signal-fire tower or coastal watchtower controlling shipping movements through the cape is supported by the visibility of the structure from approaching vessels at distances of more than 30 nautical miles. Excavated in part by Greek missions in the twentieth century.

The southernmost surviving Greek pyramid, on the headland that controlled all maritime traffic between the eastern and western Mediterranean for the entire Classical period.
