Situated by the village pond is the Cage or ‘lock-up’, a domed-shaped building bearing the inscription ‘Do well. Fear Not. Be sober. Be Vigilant’. The building served as a temporary prison for those accused of offences, until the local constable took them to be charged before the magistrates at Barnet Court.

The face of Shenley has certainly changed. In 1653 there were only 36 families living there. Population fluctuated in the eighteenth century, with approximately 103 families in the early part, dropping to 60 families by 1790. The opening of Radlett railway station in 1868, two miles away, caused an increase in population in Shenley as it became easier to commute to London.
