Discover more about these records

You can explore two of the Guernsey Public Prison registers dated from 1817 to 1877. The Guernsey Public Prison was built in 1815. From Tudor Times, prisoners were held in a small facility in Castle Cornet. By the early 19th century this was no longer suitable. A new prison was built on St James Street near the Royal Court House at the cost of £11,000. The new building did not bring with it modern conditions for the prisoners. The goal was built without a sick bay, chapel, kitchen or dayroom and only one privy. Gradully conditions improved in the 1850s and 1860s with improvements to the prisoners’ diet, sanitation condition and work programs. A new prison, and the facility still used today, was built in 1878 at Les Nicolles.

Structure of the Volumes

The early Guernsey Public Prison registers have a set structure with column headers. The register was recorded in French and translations are provided below. The second volume, 1834-1877, started with individual entries for each person until 1838. Then the register skipped the years 1838 to 1857. From 1857 onwards, the register was organised into columns with headers and recorded in English.
