4. Thurgood Marshall Courthouse
A lot of the legal action takes place in the Thurgood Marshall Courthouse at 40 Centre Street on Foley Square, just next to the New York Supreme County Courthouse. The court functions as the Second Circuit Court of Appeals and the Southern District of New York, the latter of important to Billions. In the first episode of the first season, Assistant D.A. Kate Sacker runs into Rhoades and Connerty on the steps and reports that she heard that Axelrod is trying to buy an $83 million beach house in the Hamptons.
The courthouse was designed by Cass Gilbert, who also designed the Woolworth Building and the Alexander Hamilton Customs House at Bowling Green. The building with the mansard roof in the shot above is the Surrogate’s Court, home to the New York City municipal archives and another popular film location seen in Gotham and other shows.
