Ancient Mystery

The London Stone

A block of limestone set behind glass in a wall on Cannon Street, recorded by name since about 1100 and unexplained ever since. The prophecy everyone quotes about it, that London stands only so long as the stone is safe, was written by a Welsh clergyman in the 1860s.

Field Guide Entry

A stone older than its first mention

The surviving block measures 53 by 43 by 30 centimeters and is the top of something considerably larger. Petrological opinion points to Clipsham limestone from Rutland or to Bath stone, both standard material for Roman and medieval building in London. The earliest firm reference is a property list compiled between 1098 and 1108 naming a man as Eadwaker æt lundene stane, Eadwaker at London Stone, and the name itself is recorded from around 1100. It was prominent enough to identify people by: Henry fitz-Ailwin, the first Mayor of London, in office from about 1189, took his surname from living beside it. What it was originally for has never been established. The prevailing view among specialists is that it formed part of the entrance to the Roman governor's palace, which stood nearby. It has also been argued to be a Roman milliarium, a distance marker, and, on no evidence at all, a Druidic altar.

Jack Cade's sword

In 1450, the rebel leader Jack Cade entered London, struck the stone with his sword, and declared himself Lord of this city. Shakespeare put the scene into Henry VI, Part 2 and fixed it in the popular memory. No contemporary account explains what the gesture meant or why the stone was the thing to strike, which leaves the most famous moment in the object's history as opaque as the object.

The prophecy is Victorian

"So long as the Stone of Brutus is safe, so long shall London flourish" gets quoted everywhere as ancient. It was written in the 1860s by a Welsh clergyman named Richard Williams Morgan and appears in no source earlier than his own. There is a genuine medieval thread underneath it: a fourteenth-century chronicle states that Brut sett Londen ston, crediting the legendary Trojan founder of Britain, though that tradition stayed obscure for centuries. The famous line is a piece of nineteenth-century invention that took.

Moved, walled up, exhibited, returned

The stone was shifted from the middle of the roadway to the north side of Cannon Street in 1742. Between 1798 and the 1820s it was set into the wall of St Swithin's church. When the church was demolished it went into a Portland stone alcove at 111 Cannon Street in 1962. It spent 2016 to 2018 at the Museum of London while the building above was redeveloped, and returned in October 2018 to a new plinth and Portland casing, where it sits at sidewalk level behind glass.

Visiting Information

Free, outdoors, and visible at any hour. The stone sits at sidewalk level in the frontage of 111 Cannon Street, directly across from Cannon Street station, behind a glazed grille with an explanatory panel. There is nothing to book and nobody to ask.

It is small and easy to walk straight past, which most people do. The City empties on weekends, so a Sunday visit gets you the street to yourself, while on a weekday you will be reading the panel in a stream of commuters. Pair it with the Roman Temple of Mithras a few minutes west, which sits beneath a modern office building and is also free to enter.

In 1816, a sentry at the Jewel House reportedly bayoneted a bear-shaped apparition and died of shock days later. In October 1817, Edmund Swifte, Keeper of the Crown Jewels, said he threw a chair through a glowing, cylinder-shaped apparition in the same building.

A London hotel that opened on June 10, 1865, and served as BBC offices and studios from 1941 to 1986. In July 1973, newsreader James Alexander Gordon said he threw a boot at a figure in Victorian evening dress in Room 33 and watched the boot go straight through it.

Shell Grotto

Kent, England, United Kingdom

On May 12, 1838, a Kent newspaper reported that workmen digging at Belle Vue Cottage in Margate had struck "a large stone" and found under it a grotto "completely studded with shells." The chalk passages run about 70 feet to a rectangular chamber lined, by the owners' estimate, with 4.6 million shells. Nobody knows who made it or when. The Grade I listing calls it most likely early 19th century, and a 2005 survey proposed a medieval chalk mine, probably reworked in the 1700s. The schoolmaster's daughter said her brother had crawled in before the official find.
