Fleet Prison in London held prisoners, on and off, between 1197 and 1844. In the 18th century it held debtors and people who declared bankruptcy, and it ran as a for-profit enterprise, charging prisoners to remove their leg-irons as well as for food and rent.
The Caledonian Mercury, October 5, 1727 says that Jewish prisoners in Fleet Prison built their own sukkah to celebrate the Sukkot holiday.
The Jews of the prison must have paid a great deal to be able to celebrate Sukkot.
