Batman's secret lair beneath Wayne Manor is housed in a series of subterranean caves. It serves as his command center for both local and global surveillance, as well as housing his vehicles and equipment for crime-fighting and as the headquarters of the Bat-Family. As a cutting edge facility for intelligence and technology, bolstered by not only the latest Earth technology but advanced materials and tech from Batman's various allies, the Batcave features a crime lab, a personal gymnasium, full service medical facilities, specialized training areas for Batman and his allies, a wide array of memorabilia, and a large colony of bats. Several entrances are cleverly concealed to allow Batman to enter and exit the cave in secrecy.
There is a smaller auxiliary Batcave secreted beneath the headquarters of Wayne Enterprises, and several emergency supply depots are strategically positioned around Gotham City.
