Batcave

The  Batcave  is Batman 's primary base of operations, in a cave system located under Wayne Manor.

History
Bruce Wayne discovered the caverns when he fell down a well in his youth.

After becoming Batman, Wayne would revisit the caves to use as a sanctum and to store his then-minimal equipment. Realizing that it would make a good base, with the assistance of  Alfred Pennyworth, he created a stronghold for his fight against crime.
