Tower of London skeletons: more than 20 found, some likely plague victims

Archaeologists working inside the Tower of London have uncovered more than 20 human skeletons beneath the historic fortress, a discovery that is shedding new light on how Londoners coped with disease and death in earlier centuries. Some of the remains show signs that specialists say could be linked to epidemic illness, and teams are preparing scientific tests to confirm whether any were victims of the plague.

Excavation at the Tower: what was found and where

Work crews and archaeologists made the find during routine conservation and groundworks within the Tower complex. The skeletons were unearthed in a cluster, within a disturbed stratigraphic layer that suggests deliberate burial rather than casual refuse. The location — inside the protected perimeter of one of Britain’s most famous landmarks — immediately elevated the find’s significance for both historians and heritage managers.

Evidence pointing to epidemic-era burials

Initial examinations by osteologists noted features often associated with rapid, mass interment: shallow graves, tightly grouped skeletons, and minimal grave goods. While these clues do not by themselves prove the cause of death, they fit patterns known from documented plague burials elsewhere in England.

• Clustering of burials — multiple bodies placed in a small area rather than individual, long-term cemeteries.
• Simple burial posture — bodies laid flat without elaborate markers or coffins.
• Demographic range — preliminary age and sex estimates indicate adults and younger individuals were among the dead, consistent with epidemic mortality profiles.

Scientific testing planned to identify plague victims

Researchers will apply a suite of laboratory techniques to the remains. The goal is to establish dates, health status, and whether any individuals carried the bacterium Yersinia pestis, the pathogen responsible for historic plague outbreaks.

Key analyses to be performed

1. Radiocarbon dating to narrow down the century or specific decades when the burials occurred.
2. Ancient DNA (aDNA) screening to detect genetic traces of Yersinia pestis and other pathogens.
3. Osteological assessment to document trauma, chronic disease, and nutritional markers on the bones.
4. Isotope analysis to reveal geographic origins and diet, which can help reconstruct life histories.

What this tells us about London’s past public health crises

Mass burials across England are often associated with major disease outbreaks, such as the Black Death in the mid-14th century and later waves of plague through the 16th and 17th centuries. Finding potential plague victims within the Tower grounds adds nuance to our understanding of how contagion, burial logistics, and urban pressures intersected in a fortified site that also functioned as a royal palace and prison.

• It suggests emergency burial solutions may have occurred even inside highly controlled, politically important compounds.
• It highlights how rapid-onset mortality affected people of different statuses and occupations.
• It provides material that could clarify whether outbreaks at particular times affected military, administrative, or civilian populations differently.

Heritage management and ethical handling of remains

Because the Tower of London is a World Heritage Site managed by Historic Royal Palaces, the find triggers established conservation, legal, and ethical procedures. Specialists must balance scientific inquiry with respect for the deceased and compliance with current legislation governing archaeological human remains.

Steps taken by custodians and archaeologists

• Secure removal and documentation of the remains by licensed archaeologists.
• Detailed recording of the burial context, including photographs, plans, and stratigraphic notes.
• Consultation with heritage bodies to determine permissions for sampling and analysis.
• Plans for appropriate reburial or curation depending on the outcome of scientific tests and legal requirements.

Broader implications for research and public engagement

Beyond immediate forensic and historical answers, the discovery creates opportunities for multidisciplinary research and public interpretation. If plague DNA is detected, these individuals could help map the spread and evolution of Yersinia pestis in London. Even absent pathogen confirmation, the burials contribute valuable data on mortality, burial customs, and urban life during times of crisis.

Museum teams and historians are preparing to share findings with the public through exhibitions, lectures, and digital content as analyses progress, ensuring the story of these individuals informs both scholarship and collective memory.

Next steps as specialists continue their work

Laboratory results are expected to take months. Until then, conservators will preserve sampled material, and archaeologists will complete contextual studies that include reviewing archival records for references to outbreaks, burial regulations, and Tower history that might explain why these people were interred where they were. The investigation remains active, and further announcements will follow as scientific evidence clarifies the identities and causes of death of those recovered.
