Ever since production started on Batman v
Superman: Dawn of Justice in Detroit, we know
that the city has been doubling for Washington
D.C. and Metropolis. Today, new photos from
Twitter users Tim Reinman and Tim Malin reveal
that the city is also being used for parts of
Gotham, particularly, the Gotham City Jail. Take a
look at the photos

These photos have some fans wondering whether
the Gotham City jail's presence hints at an
appearance by Commissioner Gordon. Of course,
that hasn't been confirmed at this time, but stay
tuned for more photos and videos from the set of
Batman v Superman: Dawn of Justice, as
production continues in Detroit.
In the DC Comics , the Gotham Jail served as a
temporary holding facility before the major
offenders were shipped off to Stonegate
Penitentiary or Arkham Asylum. It remains to be
seen how the building will be used in Batman v
Superman: Dawn of Justice, or if it will also be
used in the impending Justice League movie.
