The museum was founded in 1979 by Audrey and Harold Swindells in the basement of their house in Great Pulteney Street. In 1985, it moved to a home in Broad Street. This was the site of Bath's main Post Office from 1822 to 1854 and the building in which the first recorded posting of a Penny Black took place on 2 May 1840.[1] It was designated by English Heritage as a grade II listed building.[2]
The museum's collections included: biographies of key figures involved with the development of the Post Office and connected with Bath, such as Ralph Allen, John Palmer and Thomas Moore Musgrave; a history of the post from 2000BC to the current day and a history of the British postbox.
Due to vastly increased rent from 2003, the museum had to move out of the Broad Street building and on 7 November 2006 it reopened on a much smaller scale in the basement of the post office building at 27 Northgate Street.Шаблон:Citation needed
In September 2023, shortly after the death of its founder Audrey Swindells and 44 years of operation, the museum closed when its lease expired.[3]
