Pyramid of Hellinikon
Argolis, Peloponnese, Greece
Pyramid-shaped stone structure. Height: 9 m. Date: Late 4th century BCE according to archaeological consensus; a 1995 thermoluminescence test indicates c. 2720 BCE ± 580 years, a date that is disputed.
Watchtower or funerary monument. Thermoluminescence places the structure in the same period as the Egyptian pyramids, but this dating is not widely accepted.
