There are displays on post boxes through the years, and a look at the life and times of key figures involved in the establishment of the British postal system, including Ralph Allen, Thomas Moore Musgrave, and John Palmer.
There is a special collection about the earliest British system of postmarks and stamps, with late 17th century letters bearing a 'Bishop mark', a stamp named for Henry Bishop, Postmaster-General under Charles II.
The oldest object on display is a clay tablet 'letter' dating to about 2000 BC, and an Egyptian papyrus from around 1200 BC. Modern by comparison are displays on Charlemagne, King of the Franks, who around 850 AD revived the old Roman postal service in areas of his empire.
Learn about the system of 'franking', which allowed the nobility to send letters free of charge, and how this much-abused system came to an end in 1840 when Rowland Hill instituted the uniform penny postage service.
