There are over 5,000 bodies under a school in London. The children walk past one of them every morning on their way to class.
The school is in Charterhouse Square, just north of the City, near Barbican. Quiet streets. A garden in the middle. An independent school on the south side where parents drop their children off and go to work. Inside the school building, there is a museum. In that museum, there is a reconstructed grave, lit by electric candles on all sides. The grave belongs to a plague victim from 1348. The children walk past it on their way to class.
Beneath that school. Beneath that garden. Beneath the street itself. Thousands of people. Modern estimates suggest over 5,000 in the broader West Smithfield burial area alone. They have been down there since 1348.
The Black Death arrived in England in the winter of that year. Nobody in London had seen anything like it. A quarter of the city's population would eventually die. The churchyards filled within weeks. The parishes ran out of space, then out of coffins, then out of time. The dead needed somewhere to go, and they needed to go there quickly.
So they dug pits.
Many of those who died within the City of London were taken outside the city gates. West Smithfield, which was then open ground beyond the walls, became one of the primary sites. What the Crossrail excavations later revealed surprised the archaeologists. The bodies had not been thrown in carelessly. They were laid in rows, individually, with some degree of order, even as the city was collapsing around the people doing the burying. In the middle of catastrophe, someone was still trying to do this with dignity. Then the city grew over them.
Charterhouse Square has never been built on. That patch of open ground has remained open ground for seven centuries, because at some level the city always knew, even when it half forgot, that something was underneath. A monastery was founded next to the burial site in 1371, built specifically to pray for the souls of the dead beneath the ground. The monastery eventually became a school. The school is still there. The candles still burn beside the grave inside it.
In March 2013, workers building the Crossrail tunnel beneath the square unearthed twenty-five skeletons. Scientists extracted DNA from the teeth. They found Yersinia pestis, the bacteria that caused the Black Death, preserved in the remains after almost seven hundred years. It was the first direct physical confirmation that these were plague victims. There were multiple periods of burial here, including the main Black Death phase of 1348 to 1349, a return in 1361, and further outbreaks into the early fifteenth century, as the disease came back again and again to the same ground. Charterhouse Square is not the only place.
Beneath the streets around Aldgate Underground station lies a plague pit from the seventeenth century. A single pit in that area reportedly received over a thousand bodies in just a few days. Between 2011 and 2015, archaeologists recovered more than 3,000 bodies from the former Bedlam burial ground near Liverpool Street, a site that held victims of both the medieval plague and the Great Plague of 1665. Modern Liverpool Street station runs directly through the middle of it.
The commuters waiting on the platform at Aldgate are standing on it. The people rushing through Liverpool Street on an ordinary Tuesday are passing over it. The children whose parents drop them at the gates of a school in Charterhouse Square are walking across it every single morning.
None of them are doing anything wrong by being there. The city had to keep building. Life had to continue over the dead, because it always does. But something shifts when you know. When you understand that the ground beneath a perfectly ordinary morning in London has been holding all of this, quietly, for seven hundred years.
The past is not far away. In this case, it is right underfoot. The next time you walk through the City, or wait on a platform, or cross a quiet square and wonder why it was never built on, you might already be standing on the answer.
Now you know it.
If you know someone who walks through London every day, I think they should know it too.
