Beaumaris Gaol, located in Anglesey, Wales, opened 1829 and closed in 1878. Whilst only holding a maximum of 30 prisoners at any given time, it still hosted two executions and one attempted escape[1].
The Gaol is now a museum[2], and lists as one of its highlights an original treadmill, the purpose of which was to punish the prisoner’s but also to utilise their labour to pump water to the top floor of the gaol[3].
