Gotham City Hall was the chief administrative building of Gotham. As such, it was the main workplace for members of the Gotham City Council inlcuding the Mayor of Gotham.
During Rupert Thorne's tenure as chairman of the City Council, the place was used as a meeting place for Thorne and his cronies. He also used the basement of City Hall for his criminal operations such as blackmailing and torture.
