By 1773, the prison population at the New Gaol was getting so large that the city began plans for a new prison. Bridewell was started in 1773. The building was finished in 1775 but before it saw much use the war happened, and the British started to fill it with American POWs. When the war ended, this building went back to its intended use - holding local criminals and debtors. I can only hope the new government eventually installed windows and started work on the catering.
