The Cloisters Museum served as headquarters for Nightwing during his stay in New York City. Dick served as the museum's curator by day and used it as his base of operations by night. Green Lantern John Stewart redesigned the building to suit Dick's needs and the JSA helped with construction.
Despite the technological design security installed by the JSA and Stewart, Barbara Gordon managed to bypass the Cloister's security and as a favor for Dick, she improved the security system of the place.
