There are two unusual pillar boxes in Warwick that stand at the East and West gates of the city. They were cast in the mid 1800s in the shape of Doric columns by the Eagle Foundry in Birmingham. They date from a time when the design of pillar boxes was not standardised giving rise to experimental designs that included vertical instead of horizontal slits and strange shaped boxes. These pillar boxes have an attractive fluted design that is rare today.
