S.T.A.R. Labs owned a hall which included a hangar. It had since been abandoned up until Team Flash, Team Arrow, the Legends, and Supergirl used it as a base of operations while taking on the Dominators.
The hall was originally a facility for S.T.A.R. Labs for a range of their operations including aerospace due to it having a plane hangar in the back. It became defunct like most of S.T.A.R.'s facilities after the particle accelerator explosion in 2013. It was later brought into service again by Team Flash after the Dominators invaded in Central City, bringing in their allies from Star City, Earth Thirty-Eight, and the temporal zone. When Thea asked about the hall, Barry explained its status to her and that he was currently the owner of the base since Reverse-Flash's "passing".

- The S.T.A.R. Labs hall is a reference to the Hall of Justice, a headquarters for the Justice League. It was referred to by this name in the script for the DC's Legends of Tomorrow episode, "Invasion!".
- The exterior bares a striking resemblance to Cincinnati Ohio's Union Terminal, the building the Hall of Justice was based upon.
