Terminal Dogma
Terminal Dogma is the deepest, most secret level of Nerv headquarters under Tokyo-3, accessible only to those with the highest level of clearance (Gendo, Fuyutsuki, and Ritsuko Akagi, but not Misato). Within Terminal Dogma is the "LCL production plant" -- actually, the live Angel Lilith restrained by being crucified to a giant cross, and impaled on the Spear of Longinus, Lilith's blood forming an entire lake of LCL. The Eva graveyard for failed prototype Evas, and the cloning facilities to produce copies of Rei Ayanami, are also located here.
