The River Effra was an open stream through south London until the 1820s. It rose in Norwood, ran past Herne Hill into Brixton, and emptied into the Thames at Vauxhall. The Victorians culverted it. It still floods. There are cast-iron plaques in the pavement marking where it runs. Most people walk over them without looking down.

City context
London is a city built on its own buried layers. This self-guided audio walking tour goes down to the Roman temple of Mithras under a glass tower, the red ash layer left by Boudica, the plague pits and buried rivers beneath the streets, the outcast dead at Cross Bones, and the Tudor graves in the Tower. We keep the documented history separate from the city's folklore.
Tour chapters
Beneath the European headquarters of Bloomberg, on the banks of a buried Roman river, sits a temple to a Persian god that a Roman veteran built around AD 240. The river is gone. The temple was rebuilt seven metres down. You can visit it for free.

In AD 60 or 61, the Iceni queen Boudica burned Roman Londinium to the ground. The fire was hot enough to fuse clay into a red-brown layer that London archaeologists still hit two metres down. It is under the City. It is under your feet. The official plaques don't mention her.
Londinium Original Roman Basilica Site
In 1665, the parish of St Botolph Aldgate dug a single mass grave large enough to hold over a thousand plague victims. Daniel Defoe described the pit personally in A Journal of the Plague Year. Crossrail engineers hit the same bones in 2013. The site today is partly a roundabout and partly the car park of a Sainsbury's.

On 30 September 1888, hours after the Ripper's double murder, a constable found a piece of bloody apron and a chalk message on the wall above it. The Commissioner of the Metropolitan Police personally ordered the message wiped off before it could be photographed. The single most important physical clue in the most famous murder case in history was deliberately erased to prevent a riot.
Goulston Street
On 4 May 1978, a 24-year-old Bangladeshi clothing worker named Altab Ali was stabbed to death by three teenagers as he walked home from work. The park where he was killed had previously been the bombed-out ruin of a medieval church. In 1998 it was renamed for him. Two erasures on a single patch of grass.
Altab Ali Park
On the third stair of the unfinished Bethnal Green Tube shelter, on 3 March 1943, a woman fell. In the next 90 seconds, 173 people, mostly women and children, were crushed to death. There were no bombs that night. The press were forbidden to report it for two years. The first plaque went up in 2007.
Bethnal Green
From 1569 to 1738, the burial ground of the original Bethlem Royal Hospital — Bedlam — accepted around 30,000 of London's mental-asylum patients, plague victims, and unclaimed dead. In 2015, Crossrail engineers exhumed 3,000 of them to lay the Elizabeth Line. The rest are still down there. The trains run directly through.
Liverpool Street
Bunhill Fields started as a 1665 plague-emergency cemetery and became, for two centuries, the burial ground of every Nonconformist, dissenter, and Quaker who refused to lie in Anglican consecrated earth. Defoe is here. Bunyan is here. Blake is here. They are buried side by side outside the City wall because no Anglican churchyard would have them.
Bunhill Fields Burial Ground
London's second river, the Fleet, ran openly from Hampstead Heath to Blackfriars from Roman times until the eighteenth century, when the city covered it stage by stage. There is a manhole on Ray Street in Clerkenwell where, if you crouch and listen, you can still hear the river running below the grating.
The Sekforde
After the Great Fire of 1666 burned 13,000 houses and 87 churches, London needed someone to blame. They got a confession from a French watchmaker named Robert Hubert. His confession was riddled with errors. He couldn't have lit the fire — he wasn't even in England the day it began. The mob wanted a foreigner. He was foreign enough.
Monument to the Great Fire of London
Christopher Wren's church of St Dunstan-in-the-East was hit by German incendiaries in 1941 and burned to its outer walls. The City of London never rebuilt it. They turned the shell into a public garden. Vines now climb the bombed nave. Office workers eat their lunch inside the ruin. Most of them have no idea what they are sitting in.
St Dunstan in the East Church Garden
On a small unconsecrated patch of Southwark earth, fifteen thousand sex workers, paupers, and unbaptised children were buried over four centuries. The Bishop of Winchester licensed the women to work, then refused them Christian burial when they died. The site is now a chain-link fence covered in ribbons. Locals come on the 23rd of every month to read out the names.
Crossbones Graveyard & Garden of Remembrance
In 1736 the Mohegan sachem Mahomet Weyonomon sailed from Connecticut to ask George II to stop the English settlers stealing his tribe's land. He never met the king. He died of smallpox in lodgings in Aldermanbury and was buried in unmarked ground at Southwark Cathedral because foreigners weren't allowed inside the church. The Mohegans paid for a memorial. It was finally installed in 2006 — 270 years late.
Memorial to Mahomet Weyonomon
From the late twelfth century until 1783, the Tyburn Tree triangular gallows stood on what is now a small traffic island three lanes from Marble Arch. It hanged Catholic priests, debtors, witches, dissenters, and ordinary thieves. The exact number of executions runs into tens of thousands. The river Tyburn still runs beneath the spot. The plaque is the size of a pizza.
Site of Tyburn Tree
Every commuter at Sloane Square Tube station stands directly beneath a buried river running through a cast-iron pipe slung above the District Line platform. The pipe was installed in the 1860s. The river is the Westbourne. Look up. It is, almost certainly, the only place in the world where a public train platform passes underneath an active river that has been there for thousands of years.

On 7 November 1974, the 7th Earl of Lucan beat his children's nanny, Sandra Rivett, to death with a length of lead piping in the basement of his estranged wife's Belgravia townhouse. He had mistaken her for his wife. He vanished. The world remembers him. Almost nobody remembers her. The house has no plaque.

From a Persian temple under Bloomberg to the platforms where the Parthenon Marbles hid out the Blitz. Roman ash, Bedlam's burial ground, the scapegoat of the Great Fire, a bombed church turned garden, a mile of Cold War tunnel under High Holborn, and the beer wave that drowned eight people at an Irish wake. Eight stops through the City and its western edge.
Aldwych was a failing branch-line Underground station that found its purpose during the Second World War, when the tunnels between it and Holborn were used to shelter East-End families at night and to hide the British Museum's antiquities by day, including the Elgin Marbles, which spent the entire war underground in the dark, three feet behind the people sleeping on the platform.
Aldwych Underground Station (closed)
Thirty metres beneath High Holborn there is a mile of brick-lined tunnel that was built as a Blitz shelter, occupied at the end of the war by Britain's secret-warfare service, then turned into the British end of the first transatlantic telephone cable, the Moscow-Washington hotline, and a Cold War nuclear-strike telephone exchange. The road above has no plaque.

On the evening of 17 October 1814, a 22-foot iron-hooped vat at Meux's Horse Shoe Brewery on the corner of Tottenham Court Road and Great Russell Street ruptured. Three hundred thousand gallons of porter beer surged out, took down the brewery's rear wall, and poured into the basement tenements of the St Giles Rookery. Eight people drowned. Five of them were at an Irish family's wake for a dead two-year-old. The coroner ruled it an act of God.

Plague pits at Aldgate and Charterhouse Square, where Crossrail brought up Black Death skeletons with Yersinia pestis still in their teeth. The Ripper graffito a Commissioner scrubbed before dawn, Altab Ali's park, the Bethnal Green stairway disaster, and Arnold Circus, a bandstand standing on the rubble tomb of London's worst slum. Six stops through what the East End buries and tidies.
In 1348 a Flemish knight named Sir Walter de Manny bought thirteen acres of marshy ground outside the City wall and turned it into an emergency cemetery for the Black Death. Maybe fifty thousand people went into it. The land later became a Carthusian monastery, then a Tudor palace, then an almshouse. The pit is still there. In 2013 Crossrail's tunnels passed through the edge of it and brought up twenty-five of them.
Charterhouse Square
The Old Nichol was the worst slum in late-Victorian London, five thousand seven hundred people in seven hundred and thirty houses, with one in four children dying before their first birthday. The London County Council demolished it from 1893. They built the world's first council-housing estate on top, with a circular garden at the centre on a raised mound made of the slum's own bricks. The bandstand on the mound is the headstone.

Bunhill Fields, where the dissenters lie unconsecrated; Cross Bones, the outcast dead of Southwark; a Mohegan sachem buried by a king; and the River Effra, the buried south London stream that still runs to the Thames beside MI6. Four stops for the Londoners the city kept outside its walls.
The River Effra was an open stream through south London until the 1820s. It rose in Norwood, ran past Herne Hill into Brixton, and emptied into the Thames at Vauxhall. The Victorians culverted it. It still floods. There are cast-iron plaques in the pavement marking where it runs. Most people walk over them without looking down.

The Fleet under Ray Street, the Tyburn gallows under a traffic island, the Westbourne in a pipe over Sloane Square station, the murder of Sandra Rivett, and the ghost Jubilee platforms sealed under Trafalgar Square. Five stops on the London the map stopped admitting was there.
When the Jubilee line extension opened in November 1999, the original Jubilee terminus at Charing Cross was abandoned. Two fully-finished platforms with their original 1979 design intact have been quietly maintained ever since, used for film shoots, reversal moves, and the occasional emergency. Tens of thousands of commuters walk over them every morning without realising the trains stopped coming twenty-six years ago.

At Guildhall Art Gallery, John Blanke appears twice in the Westminster Tournament Roll: a Black trumpeter in Henry VIII's royal livery, paid the same as the men around him, preserved in a court image that almost never preserved people like him. At the Tower, Anne Boleyn was buried in an arrow chest under the Chapel of St Peter ad Vincula because nobody had ordered a coffin. Six years later Catherine Howard, probably eighteen, was buried nearby and then lost so thoroughly that the memorial under the chapel floor is still partly a guess. Three stops through Tudor power as paperwork, spectacle, execution, and bones.
John Blanke is the first named Black person in English recorded history. He played trumpet at Henry VII's funeral and Henry VIII's coronation. He was painted twice, in colour, in the Westminster Tournament Roll of 1511. He wrote, or had written for him, a polite letter to Henry VIII asking for his wages to be doubled. Henry VIII signed it. The pay rise went through. Then, around 1512, Blanke disappears from the record.

Anne Boleyn was beheaded with a sword on Tower Green on 19 May 1536. Nobody had ordered a coffin. They put her body and head into an empty elm chest that had once held bow staves and buried her under the floor of the Chapel of St Peter ad Vincula. There she stayed for three hundred and forty years. In November 1876, when Queen Victoria's restoration of the chapel disturbed the chancel pavement, Doyne Bell looked at the bones and noted: the cervical vertebrae of one of the women were singularly small and delicate.
Chapel Royal of St Peter ad Vincula, Tower of London
Catherine Howard was Henry VIII's fifth wife, executed on Tower Green on 13 February 1542. She was probably eighteen. She was buried, like her cousin Anne Boleyn six years earlier, under the floor of the Chapel of St Peter ad Vincula. When Doyne Bell exhumed the chancel in 1876, he could not identify her bones. The marble memorial in the floor today carries her name on a guess.
