The Tumulus Tomb of Amphipolis lies on the hill of Kasta inside a 500-meter long surrounding wall of marble and limestone. The Marble wall is almost a perfect circle 3 meters high with a cornice of marble from the Aegean Island of Thassos. This great Tomb and the surrounding wall with its special base and unique design is likely the work of the Architect Deinokratis, who lived at the time of Alexander the Great. Deinokratis and was Alexander's chosen Architect and also a very important person in the time of Alexander.
The Entry of the Tomb is 13 steps down from the surrounding Wall. The Entry Arch contains two headless/wingless Sphinxes, amazing works of classic art. In front of the Arch and Sphinx Portal there is a Limestone wall protecting and concealing the entire entry of this vast tomb. The design of the Entry and surrounding wall are unique to the ancient Greece world.
