Royal Mail Mount Pleasant Sorting Office, Postal sorting facility in Islington, England
The Royal Mail Mount Pleasant Sorting Office is a postal classification facility in the Islington area of London, featuring distinctive red brick Victorian architecture. The building incorporates tall windows for natural light throughout work areas and operates modern automated systems to handle the high volume of mail and packages processed daily.
The facility opened in 1889 on the site of the former Coldbath Fields Prison, after Frederick Ebenezer Baines championed the creation of a central sorting hub for British postal operations. This location choice represented a major shift in how mail infrastructure was organized to serve London's expanding needs.
The name Mount Pleasant refers to the elevated area where the building stands, reflecting its original geographical setting. Visitors can observe how the sorting office has become a landmark that shapes the character of the Islington neighborhood.
The site is best visited during regular weekday hours when mail processing operations are at their peak and activity is most visible. Visitors should note that this is primarily an active postal facility, so general access may be limited apart from organized tours or the museum located within the building.
Inside the complex sits the Postal Museum with access to a preserved section of the London Post Office Railway, an underground mail transport system that operated from 1927 to 2003. This railway was an innovative solution for moving mail quickly beneath London's streets and remains a remarkable piece of postal history.
