The aging 12th precinct stationhouse had faulty plumbing, cracked walls and ceilings, lousy air conditioning/heating and outdated furniture, but somehow, the police officers survived.

During the show's last season an antique firearm discovered in the stationhouse revealed the building was once Theodore Roosevelt's headquarters when he was President of the New York Police board in the 1890s. The building was quickly declared an historical landmark and the officers assigned to the building were transferred but not before Barney Miller was promoted to Deputy Inspector.

On the last episode, (9/9/82) before leaving the building for the very last time, Barney, alone in the deserted squad room, remembered (via flashbacks) all the staff who had come before, both living and departed.

TRIVIA NOTE: The prop holding cell (bars and all) used to detain suspects on the series was donated to the Smithsonian Institution in Washington, D.C. The interior design of the TV stationhouse was inspired by a real one that producer Danny Arnold had once visited after putting up bail money for some of his production crew who had been arrested for pitching pennies.
