The burial complex, which doesn’t appear to be looted, was found outside the ancient Macedonian city of Amphipolis in 2012, but its entrance wasn’t located until August.
Throughout autumn, stunning new finds emerged almost daily, including a large floor mosaic depicting Pluto’s abduction of Persephone.
The dig has not been without controversy. Greek Prime Minister Antonis Samaras pre-empted the archaeologists in announcing the discovery.
Groups such as the Association of Greek Archaeologists have complained that the subsequent relentless media coverage, floods of tourists and increased risk of looting are compromising ongoing work at the site.
