Black Archive

The Black Archive was a secret vault maintained by UNIT.

Function
It functioned as a depository of everything that shouldn't exist on Earth but did anyway, and required a UNIT level one clearance to gain entrance. (SJA: Enemy of the Bane)

History
The Doctor, during either his second or third incarnation, aided in the foundation of the Black Archive. (IDW: Don't Step on the Grass)

In 1972, UNIT recovered the Tunguska Scroll and put it in the Black Archive. In 2009, the Brigadier smuggled Sarah Jane Smith into the archives to steal the scroll. (SJA: Enemy of the Bane) During the same year, the Tenth Doctor sent Martha Jones there to fetch information on the Krynoid virus in the hopes that it might hold a key to stopping the Enochian invasion in Greenwich Park.
