Aldgate and the mass graves of the Great Plague

Place card

Place: two related but distinct sites. St Botolph without Aldgate represents an eastern parish in which the Great Plague of 1665 devastated whole households. The former New Churchyard, also called the Bedlam burial ground, lay about a kilometre west near present-day Liverpool Street; archaeologists found and genetically confirmed a mass burial of plague victims there.

Address: St Botolph without Aldgate, Aldgate High Street, London EC3N 1AB. The New Churchyard excavation occupied the Broadgate and Elizabeth line worksite at Liverpool Street; it is now transport infrastructure, not an open archaeological site.

Nearest station: Aldgate for the parish; Liverpool Street for the confirmed burial. Walk between them along Houndsditch and Bishopsgate.

Period: Great Plague, 1665–66; New Churchyard used from 1569 to 1738; Crossrail excavation, 2011–16; Yersinia pestis DNA confirmed in 2016.

Themes: Great Plague; parish registers; Bills of Mortality; searchers of the dead; shut houses; poverty; mobile labour; night burial; coffins in a shared pit; ancient DNA; Underground folklore; the myth that the Great Fire ended plague.

Access: St Botolph follows its own opening schedule; respect services. At Liverpool Street, film only from public areas and do not obstruct passengers. Do not promise a visit to a “plague pit”: the excavation is covered by the station, and the remains were destined for reburial after study.

The setting

Imagine Aldgate in September 1665. Beyond the City’s eastern gate live porters, craftspeople, sailors, traders and families renting crowded rooms. Red crosses appear on doors. Watchmen stand outside shut houses. At night a cart collects the dead.

Three and a half centuries later, London builds a railway. Near Liverpool Street, archaeologists open a rectangular pit. Forty-two people lie inside it: in coffins, in rows, three or four levels deep, with almost no earth between them. Five tested teeth preserve Yersinia pestis DNA.

This is London’s first archaeologically confirmed mass burial from the Great Plague. It is not beneath Aldgate station, and the people were not thrown chaotically from a cart. Even inside a common pit, they had coffins.

About a kilometre separates the catastrophe documented in Aldgate parish from the Liverpool Street discovery. Urban legend compresses that distance into one phrase: “a plague pit under the Tube.” History must follow the entire route from parish register to laboratory tooth without losing the people on the way.

The story

A parish beyond the gate

St Botolph without Aldgate means outside the gate. In the seventeenth century, this was a threshold between the regulated City and a rapidly growing eastern suburb. Roads carried people towards Essex, riverside employment and markets. Those who lived here depended on the movement of goods and bodies.

The parish was large and socially mixed. It included prosperous householders but also poor families, servants, day labourers and single men in lodgings. Mobility complicates reconstruction: a man might work beside the Thames, sleep in one parish and possess only a weak link to its administrative community.

During plague, crowding intensified contact, poverty limited escape, interrupted trade destroyed income and quarantine could confine healthy people beside the sick. “The rich fled and the poor stayed” is too absolute, but the ability to leave was radically unequal.

Historical-demographic work counts 4,555 St Botolph Aldgate burials in 1665, nearly seven times the preceding decade’s average. A London Lives reconstruction suggests death touched about two thirds of parish households. These are parish totals, not the capacity of one grave beside the church. They measure the social radius of the disaster.

How London counted its dead

London had no modern cause-of-death register. Parish clerks sent weekly returns to the Company of Parish Clerks. Searchers of the dead, generally older women with practical experience, examined bodies and named a likely cause. Totals appeared in printed Bills of Mortality.

The bills allowed readers to follow infection by parish. In the worst September week, more than seven thousand plague deaths were officially reported. Yet a bill was simultaneously a count, an administrative instrument and the product of limited diagnosis.

A searcher had no laboratory. Families feared the word plague because it could close a house and remove income. The poor, temporary lodgers, religious outsiders and people dying away from recognised homes could be recorded unevenly. Some causes were concealed; others were honestly mistaken.

The official 68,596 plague deaths in 1665 are therefore usually treated as an underestimate, while total London mortality is often estimated around 100,000. That round figure is also a reconstruction, not a complete ledger. Bills remain powerful because they show weekly and parish variation when read with knowledge of their production.

The searcher between body and table

Later accounts caricature searchers as ignorant old women. That explanation blames individual incompetence and hides the system. Parishes selected women familiar with local life and visible signs of disease. They entered infected rooms, inspected skin and reported to the clerk. The work was dangerous, poorly paid and socially stigmatised.

Diagnosis relied on symptoms and family testimony. Buboes, spots and rapid decline might suggest plague, but co-infection and similar symptoms caused uncertainty. A plague verdict also triggered intervention. Negotiation, fear and occasional bribery were possible, but not every alternative label concealed plague: Londoners still died from childbirth, injury, smallpox, tuberculosis and hunger.

Information passed through the searcher, parish clerk, Company, typesetter and seller. At every stage, a person became a line and lines became a total. The Bill was a remarkable early system of urban statistics, but never a neutral camera.

Red cross, closed door

Plague orders required infected houses to be marked with a red cross and “Lord have mercy upon us,” guarded and closed. Authorities restricted gatherings and newcomers, demanded cleaner streets, regulated food and animals and burned fumes to correct supposedly corrupted air.

Some rules reflected miasma theory; some reduced movement; others harmed households. Shutting an entire family together increased exposure within the house. A watchman was both guard and supplier of necessities. Wealth enabled flight, influence or physical separation. Poor residents depended on parish relief.

Orders were broken, marks removed and watchmen bribed. Records of such conflict do not prove universal recklessness. They show the collision of metropolitan control with a family’s immediate attempt to survive.

Death also passed through an official chain: inspection, registration, shroud or coffin, bearer, cart and grave. The cinematic cry “Bring out your dead” should not replace the specific work done by parishes and labourers.

Where Aldgate buried

Parish churchyards were used intensively. Graves could be deepened and contain several burials; large pits might be opened during peaks. Yet every modern garden or station around Aldgate is not automatically a documented plague pit.

St Botolph’s older church was replaced in the eighteenth century, and burials of many periods lie beneath and around the site. A later engraving records a boy’s body discovered in a vault in 1742 and described as a possible 1665 victim. “Possible” matters. A later attribution without secure context or DNA is not confirmation.

Folklore places plague pits beneath Aldgate, Aldgate East and many other stations. Railway work certainly encountered human bone, but bone alone does not establish a 1665 death. A plague identification needs stratigraphy, dating, documentation or molecular evidence.

New Churchyard: space for those without space

North of the City wall near future Liverpool Street, New Churchyard opened in 1569. It is called the Bedlam burial ground because Bethlem Hospital stood nearby, but it did not serve only hospital patients. It was London’s first large non-parochial or municipal cemetery, receiving poor people, strangers, dissenters, institutional dead and those lacking secure burial rights.

That function mattered during epidemic disease. Parish government imagined population through belonging, while London contained thousands who fitted boundaries badly. New Churchyard provided ground for people whom ordinary systems struggled to place.

It operated for almost 170 years. Most of the roughly 3,500 graves excavated for Crossrail do not belong to the Great Plague. People died between 1569 and 1738 from many causes. Labelling every skeleton a plague victim erases the cemetery’s history.

The pit with forty-two coffins

In 2015, MOLA excavated an unusual group. Initial announcements estimated about forty-five people; the final figure commonly given is forty-two. Unlike individual graves around it, they occupied one rectangular space.

Bodies lined the edges in rows and were stacked three or four deep. Almost no soil separated the layers, suggesting a short burial event. This was not a disorderly dump. Nails and body positions showed thin wooden coffins. As the wood decayed, layers collapsed together.

The grave expresses urgency and ritual at once. There were too many deaths for one pit per person, yet coffins, orientation and order remained. “Mass burial” describes a shared cutting and many bodies; it need not mean contempt.

A broken Mary Godfree headstone dated September 1665 was also found nearby. It supported the cemetery chronology, but ancient DNA provided the decisive plague evidence for the group.

Five teeth and the last great London outbreak

Plague normally leaves no diagnostic skeletal mark. Researchers sampled teeth from twenty individuals; five preserved Yersinia pestis DNA. The positive results confirmed the burial’s Great Plague context.

This was the first molecular confirmation of the agent behind London’s 1665 epidemic. Historians already had symptoms, chronology and comparison, but not pathogen DNA from such a group.

Five of twenty does not mean the other fifteen died from something else. DNA decays, pathogen material is uneven and a negative test has sensitivity limits. The simultaneous burial context plus several positives supports interpretation of the pit without claiming laboratory confirmation for every person.

Comparing 1665 DNA with Black Death strains can illuminate bacterial evolution, but there is no simple “it mutated and weakened” answer. Population density, nutrition, immunity, vectors, trade, climate and public measures shaped mortality alongside the pathogen.

Why a name does not automatically belong to a skeleton

The fragmentary Mary Godfree memorial is emotionally compelling because it restores a name beside thousands of anonymous remains. It also creates a temptation. A documentary may place the stone beside an excavated face and imply that this is Mary. Unless grave position, inscription, coffin and osteological evidence form a secure chain, that identification should not be made.

Burial-ground registers are valuable but incomplete. Spellings change, ages may be absent, two people share a name and the recorded burial date is not necessarily the date of death. Later construction displaced monuments and bones. A headstone could be moved when the cemetery became crowded, while a coffin could lose every organic marker that once identified it.

Crossrail’s burial-register project used documentary research and public transcription to recover names and social context. This can reconstruct the population of the cemetery without assigning every excavated skeleton an identity. Population history and personal identification are different levels of proof.

The same caution applies when moving east to Aldgate. A person named in St Botolph’s register was buried through that parish system, but cannot simply be placed in the Liverpool Street pit because both records belong to 1665. New Churchyard received people from across London and outside ordinary parish rights. Geography, administration and burial destination must be demonstrated, not assumed.

This boundary is productive for a podcast. Present Mary’s inscription as evidence that September 1665 reached this ground. Present the forty-two coffins as a group confirmed through context and DNA. Then say plainly that the sources do not permit us to place her among them. Refusing a false reunion respects the very individuality the name seems to promise.

People behind the Aldgate total

One weekly number hides different lives. A porter lost work when trade stopped. A widow might become a searcher because dangerous, stigmatised work offered a small income. A watchman had orders to keep residents inside and a duty to bring food.

Historians link registers with hearth taxes and households, but many connections fail. St Botolph contained single men and temporary workers difficult to attach to one address. A burial count represents administrative visibility as well as death.

Do not invent one family and claim its members occupy the Liverpool Street pit unless records and remains are securely matched. The power lies in combining scales: parish documents expose social catastrophe; archaeology shows the treatment of bodies.

Fire did not destroy plague

A familiar school ending says the Great Fire of 1666 burned rats, fleas and infected houses, ending the epidemic. Chronology contradicts it. Mortality had already fallen sharply during the winter of 1665. Authorities still issued plague orders in May 1666, and people died from plague after the September fire.

The fire destroyed the central City but spared heavily affected suburbs including Whitechapel, Clerkenwell and Southwark. No instant sanitation revolution followed. Why major plague did not return to London has several ecological and social explanations, not one fiery solution.

The myth survives because it joins two disasters into a moral arc: cleansing fire ends disease and creates a new city. Reality offers no single hero or final cause.

How a kilometre disappears

Aldgate is linked to plague through documents: its parish suffered extreme mortality. Liverpool Street is linked through archaeology: a confirmed mass burial was found there. The Underground joins them in modern imagination.

A station is an attractive coordinate—familiar, accessible and already underground. “Bones were found while building railways” becomes “the station was built around a plague pit,” then migrates to neighbouring station names. The Tube map compresses Aldgate, Aldgate East and Liverpool Street just as legend compresses evidence.

A careful route is more atmospheric, not less. Walk from the church whose register counted thousands to the station whose soil held forty-two coffins. Between them lies the real epidemic city: streets, labour, parish authority and the distance a cart travelled at night.

Preserving that distance is not pedantry. It prevents a vivid modern coordinate from swallowing two different kinds of evidence. The parish tells us how mortality moved through households; the cemetery shows how one urgent burial event was organised. Allowed to remain distinct, they explain more together than either could as one simplified “pit under Aldgate.”

That distinction makes the route honest.

People to remember

The dead of St Botolph Aldgate number 4,555 burials in one year, but were never one anonymous body. They included families, servants, mobile workers and people no register can securely attach to a home.

The forty-two people of New Churchyard shared a pit but retained coffins and ordered rows. Five positive DNA samples confirm the group context without replacing individual lives.

Searchers of the dead created the data behind Bills of Mortality. Their work was dangerous and imperfect but essential.

Watchmen, bearers and gravediggers enforced quarantine and sustained burial. They were necessary, poorly paid and exposed to infection and stigma.

Parish officers collected lists, relief, food and burial money while neighbours continued to die.

Crossrail and MOLA specialists separated one plague group from a multi-century cemetery and confirmed the pathogen through teeth.

Fact, interpretation and legend

Fact: Aldgate suffered severely. Legend: one precisely located common grave lies directly beneath Aldgate station.

Fact: forty-two people shared a Liverpool Street burial. Error: all 3,500 Bedlam cemetery skeletons were Great Plague victims.

Fact: five of twenty samples preserved Yersinia pestis. Error: the other fifteen definitely died from another cause.

Fact: several coffin layers occupied one pit. Legend: naked bodies were thrown in without order.

Fact: Bills trace the epidemic. Limit: they are not complete laboratory statistics.

Fact: the fire followed plague. Myth: it instantly eliminated infection.

The place today

Begin at St Botolph and explain without through an overlay of the wall. The present eighteenth-century church is not the unchanged 1665 building, but preserves the parish location.

Walk to Liverpool Street, marking the distance rather than calling every garden a pit. At the station, explain that archaeology is covered by infrastructure. Absence is the image: passengers cross a studied cemetery without an exposed attraction.

Do not obstruct exits or film passengers closely without consent. Use an ordered coffin diagram, not a sensational reconstruction. Check MOLA/Crossrail image rights and warn viewers before showing human remains.

End between the two flows. Data travelled from body to parish to printed bill; bodies travelled from houses to burial ground; legend travels backwards and places everything beneath one station name.
