The Imperial Standards of Length in Trafalgar Square are a set of measurement markers installed into the granite wall of the North Terrace. These bronze plaques were placed here in 1876 to provide a ready reference for traders and the public to check their measuring devices against the standard units of the day.
One fascinating aspect of the Imperial Standards is their historical importance in establishing uniformity across an empire that spanned continents. They include the yard and the foot, measures still in use in some contexts within the UK today. The existence of such public standards highlights the critical importance of trade precision in the Victorian era.
The plaques are located near the base of the staircase at the National Gallery, making them easy to visit even if you're just passing by for the artworks. Many people overlook them, making them one of London's hidden historical gems amid the hustle and bustle of Trafalgar Square.
An intriguing point about these standards is that they were public property. This was part of a movement towards transparency and fairness, ensuring everyone could access the same measurements in an era before digital precision.
A little-known fact is that although they're termed "standards," the measurements were created with scientific precision, using platinum-iridium alloy bars to create the physical representations used offsite for other official units.
