Mysteries of the Kremlin are revealed as archaeologists dig deep into its history

Descending into the basement of the 1930s-era Kremlin administration building is an eerie experience: the corridors are still lined with brown Soviet tiles and walls bear remnants of secret communication wires.
But turning off to the left or right, concrete foundations have been removed from the humid underground storage rooms, giving a glimpse at some of the best-preserved remains of early Moscow’s bustling medieval quarters.
Human bones jut out from the earthy sides of the dig, leftovers from an old necropolis for the gentry who once lived here. Beneath the drab flooring, archaeologists have marked the layered strata: 12th century, 13th century, 14th century.
Since 2014, when President Vladimir Putin ordered the dismantling of a massive Stalin-era building known as “The 14th Wing” inside the Kremlin walls, archaeologists have enjoyed unprecedented access to the premises, says Nikolai Makarov, director of Moscow’s Institute of Archaeology.

As the “territory of power,” it has been largely inaccessible for serious archaeological research.
