The New Gotham Clocktower is the base of operations of the Birds of Prey.
The clocktower was used as a secret lair by Barbara Gordon and Helena Kyle in their efforts as vigilantes, with all of the technology provided by Bruce Wayne; Dinah Redmond soon joined them, becoming known as the Birds of Prey. Dinah often practiced throwing Batarangs for training, but was noticeably bad at it.Carolyn Lance hid in the Clocktower to be less of a target when hunted down by Hawke. However, she later left to make things up with her daughter Dinah before dying.
