Penfold.

This Penfold pillarbox dating from the reign of Queen Victoria is located just south of Tower Bridge.

Between 1866 and 1879 the hexagonal Penfold post box became the standard design for pillar boxes and it was during this period that red was first adopted as the standard colour. The first boxes to be painted red were in London in July 1874.

Penfolds, which are distinguished by their hexagonal construction and acanthus bud surmounting the cap, were originally exclusively city-based, but have now been installed rural areas as well. About 300 were made, of which 150 survive. Nearly 100 replicas, made at the end of the 1980s, have also been installed.
