About the museum
Beaumaris Gaol was designed by Hansom and Welch and built in 1829 as the county prison for Anglesey. It served as the county gaol until 1878, when prisons passed from the counties to central government and its last five prisoners were moved to Caernarfon. Executions here were rare: only two hangings took place, and the best-known is the execution of Richard Rowlands in 1862 for murder. According to local tradition he cursed the church clock opposite the scaffold, and the clock is said never to have kept the right time since.
The building is well preserved. It still has its cells, a condemned cell, a punishment cell and a treadwheel that once pumped water to the upper floors of the prison, so that prisoners' labour served a practical purpose. The treadwheel is described as the only one surviving in a prison in England or Wales. The gaol became a museum of prison life in the mid-1970s and welcomes around 30,000 visitors a year.
The Beaumaris Courthouse stands nearby in Castle Street. It is more than 400 years old and is described as one of the oldest courthouses in Britain. Despite changes in the nineteenth century it kept its original character, and cases are still heard there once a year.
