The people who lived before us are often just beneath our feet, even if their tombs are sometimes forgotten. Lost under urban development, they are rediscovered when a subway, building, or other structure claims the ground for progress. Here are eight burial sites that came to light in this unconventional manner.

1. SOLDIERS' REMAINS IN ROME’S FUTURE SUBWAY

The construction of Rome's subway has unearthed everything from a 2nd-century home decorated with mosaics and frescos to a 2300-year-old aqueduct. The San Giovanni station, slated to open in 2018, will feature displays of artifacts found during its excavation, such as Renaissance ceramics and the remains of a 1st-century agricultural fountain.

Back in 2016, extension work on Line C ran into a 2nd-century military barracks with 39 rooms, likely used by Emperor Hadrian's army, as well as a mass grave of 13 skeletons. The dead may have been members of the elite Praetorian Guard, protectors of the Roman emperor. Investigations are ongoing, although officials have planned for the barracks to be incorporated into the station architecture. Its opening date remains in limbo as archaeological finds continue to slow its construction.

2. AFRICAN-AMERICAN NEW YORKERS UNDER AN OFFICE BUILDING

In 1991, construction of a federal office building revealed a colonial-era burial ground in Lower Manhattan. The graves, dating back to the 1690s, had been lost due to landfill and development, yet were identified as part of the African burial grounds that in the 17th century were located outside the old city.

Banned from interment in white cemeteries, free and enslaved Africans and African Americans had established a place to give respect to their dead, with an estimated 10,000 to 20,000 burials. Thanks to grassroots activism, including protests against continued construction, the site is now commemorated with the African Burial Ground National Monument, which opened in 2006.

It's not the sole black cemetery to be buried under development in New York: The Second African Burial Ground, dating from the 18th and 19th centuries, is located below today's Sarah D. Roosevelt Park on the Lower East Side; and in East Harlem, a 17th-century slave burial ground, discovered by construction workers at a bus depot, awaits a planned memorial.

3. PLAGUE VICTIMS IN THE LONDON TUBE

Burrowing deep under London, the ongoing Crossrail commuter rail project has exposed obscure layers of the city's past—and a treasure trove of history. Along with medieval ice skates and a Tudor bowling ball, archaeologists have identified two mass graves. One has 13 skeletons of people who probably died in the 14th century of Black Death (with DNA on their teeth still holding the plague bacterium Yersinia pestis); a larger site has 42 skeletons of victims of the Great Plague of 1665. The study of the Great Plague skeletons, excavated in 2015 by Museum of London Archaeology, similarly showed traces of the disease in their old teeth. (Luckily the bacteria is no longer active, so no need to dust off your plague doctor beak mask.)

While such "plague pits" have long been rumored—some urban legends say the London Underground had to curve to avoid messy heaps of bodies—study of the sites indicated that there was in fact great care taken with the deceased. The bodies were placed in individual coffins, giving them some dignity even in this hasty mass burial.

4. EARLY PHILADELPHIANS UNDER A FUTURE APARTMENT BUILDING

Sometimes, to borrow a line from Poltergeist, people only move the headstones when relocating a cemetery, and stray bones and coffins are left behind (digging up the dead is generally unpleasant work). That seemed to be the case with a graveyard unearthed at a construction site on Arch Street in Philadelphia in March 2017. The dozens of coffins that were discovered are believed to be part of the First Baptist Church Burial Ground, established in 1707 and supposedly moved to Mount Moriah Cemetery in 1859. The Mütter Institute spearheaded a crowdfunding campaign for analysis and reinterment of the bones, and volunteer archaeologists convened at the site, racing against time to map the grounds and remove the burials of more than 100 people. Their remains were carefully analyzed.

Archaeologists subsequently found the remains of more than 400 people at the site as construction went on in other areas. Building at the site continues, as does the grassroots-funded research on the bones (you can follow the team's progress at the Arch Street Bones Project website).

5. WOMEN AND THEIR GOLD WREATHS IN A GREEK SUBWAY SITE

In 2013, construction on a subway in Thessaloniki, Greece, turned up the grave of a woman buried around 2300 years ago. The Early Hellenistic lady was interred with a gold olive branch wreath.

Surprisingly, this wasn't the first such skeleton found during subway construction to be so regally crowned. In 2008, another Hellenistic woman was discovered with four gold wreaths and gold earrings in the shape of dogs' heads, all indicators of wealth and respectability—something marred a bit by the sewage pipe that had wrecked part of her grave.

6. ANCIENT BONES IN THE WAY OF A CANADIAN PIPELINE

While digging a trench in 2013 for a gas pipeline in Saskatchewan, Canada, a contractor noticed bone fragments in the soil that turned out to be 1000-year-old human remains.

Construction was halted so First Nations elders and archaeologists could examine the area. Ultimately, the pipeline company opted to tunnel deeper to avoid disturbing the ancient burials.

It was only one of many instances of massive infrastructure projects coming in contact with pre-colonial burial grounds. In 2017, for example, road construction in Duluth, Minnesota desecrated graves when the state's department of transportation failed to evaluate the area for artifacts prior to breaking ground.

7. HEADLESS VIKINGS IN THE MIDDLE OF A PROPOSED ROAD

Near Weymouth in Dorset, England, a mass grave of more than 50 young men was discovered in 2009 by archaeologists doing a survey before road construction began. All the victims had been killed brutally, at once, with multiple blows from a sharp weapon visible on their bones, and their heads had been severed. In 2010, researchers identified them as Vikings by radio-carbon dating the bones to 910 to 1030 CE, when the English clashed with Viking invaders. Analysis of the isotopes in the teeth indicated Scandinavian origins. Due to their lack of clothing and their similar manner of death, they were likely executed as captives. They're now part of the Dorset County Museum.

8. INDIGENT CHICAGOANS UNDERNEATH A LUXURY RESIDENTIAL DEVELOPMENT

Among the roughly 38,000 people interred beneath a neighborhood on Chicago's Far Northwest Side are the impoverished inmates of the Cook County almshouse and patients from the county insane asylum. The area was known as Dunning, and its squalid institutions were so well known that a judge in 1889 declared them a "tomb for the living." The 20 acres of the site also included a potter's field for the indigent and unclaimed, and the burials of more than 100 unidentified dead from the Great Chicago Fire of 1871.

The potter's field was revealed in 1989 during construction on luxury homes. Sewer workers who were laying pipes also turned up a corpse that was so well-preserved his handlebar mustache was still visible. Bodies were relocated to a site now called Read-Dunning Memorial Park, giving these dead some recognition in the city for the first time.

If you’ve already mastered DIY houses for birds and dogs, maybe it’s time you built one for yourself.

As Simplemost reports, there are a number of house kits that you can order on Amazon, and the Allwood Avalon Cabin Kit is one of the quaintest—and, at $32,990, most affordable—options. The 540-square-foot structure has enough space for a kitchen, a bathroom, a bedroom, and a sitting room—and there’s an additional 218-square-foot loft with the potential to be the coziest reading nook of all time.

The construction process might not be a great idea for someone who’s never picked up a hammer, but you don’t need an architectural degree to tackle it. Step-by-step instructions and all materials are included, so it’s a little like a high-level IKEA project. According to the Amazon listing, it takes two adults about a week to complete. Since the Nordic wood walls are reinforced with steel rods, the house can withstand winds up to 120 mph, and you can pay an extra $1000 to upgrade from double-glass windows and doors to triple-glass for added fortification.

Sadly, the cool ceiling lamp is not included.Allwood/Amazon

Though everything you need for the shell of the house comes in the kit, you will need to purchase whatever goes inside it: toilet, shower, sink, stove, insulation, and all other furnishings. You can also customize the blueprint to fit your own plans for the space; maybe, for example, you’re going to use the house as a small event venue, and you’d rather have two or three large, airy rooms and no kitchen or bedroom.

Humans First Arrived in North America 30,000 Years Ago, New Studies Suggest

People occupied North America by roughly 11,000 BCE, but the exact timeline of how early humans first arrived on the continent is contested. Two new studies suggest that humans were living in North America as far back as 30,000 years ago—preceding some earlier estimates by more than 15,000 years.

According to the traditional narrative, the first North Americans were big game hunters who crossed a land bridge connecting Asia to North America around 13,000 years ago. They left behind distinct, fluted arrowheads and bone and ivory tools that were dubbed “Clovis” tools. “This narrative, known as ‘Clovis-first,’ was widely accepted for most of the 20th century until new archaeological evidence showed that humans were present in the continent before Clovis,” Lorena Becerra-Valdivia, an archaeological scientist with the Universities of Oxford and New South Wales and co-author of the new studies, tells Mental Floss. “Within academia, an earlier arrival of 16,000-15,000 years ago was generally accepted.”

Her new analysis pushes back that date by several millennia. The study, “The Timing and Effect of the Earliest Human Arrivals in North America,” published in the journal Nature, looks at radiocarbon and luminescence data from Beringia, a region that historically linked Russia and Alaska, and North America. A statistical model built with this data indicates that a significant human population was living on the continent long before the Clovis era. According to the study, these humans were likely present before, during, and after the Last Glacial Maximum—the period when ice sheets covered much of North America 26,000 to 19,000 years ago.

These findings also contradict the land bridge theory. Rather than making a straightforward journey from Asia to North America and populating the southern half of the continent as the Clovis people were thought to have done, the first humans may have entered the Americas by traveling down the Pacific Coast. “These are paradigm-shifting results that shape our understanding of the initial dispersal of modern humans into Americas,” Becerra-Valdivia says. “They suggest exciting and interesting possibilities for what likely was a complex and dynamic process.”

The second, related study in Nature, ”Evidence of Human Occupation in Mexico Around the Last Glacial Maximum,” supports this new narrative. In it, researchers from institutes in Mexico, the UK, and other countries share artifacts and environmental DNA uncovered from Chiquihuite Cave—a high-altitude cave in Zacatecas, central Mexico. The tools, plant remains, and environmental DNA collected there paint of picture of human life dating back 13,000 to 30,000 years ago. The evidence shows that the site was more than just a stopping point, and the people living there had adapted to the high altitudes and harsh mountain landscape.

The two studies not only offer insight on when the first North Americans arrived on the continent, but who they were and how they lived. The Americas would have looked a lot different to humans during the Last Glacial Maximum than they did to the Clovis people millennia later. The fact that the first North Americans left behind far fewer artifacts than the Clovis people shows that their populations stayed relatively small. “Humans at Chiquihuite Cave would have faced the harshness of the Last Glacial Maximum, the peak of the last Ice Age, which would have kept their population at a low density,” Becerra-Valdivia says. “Clovis peoples, in contrast, thrived well after the last Ice Age, expanding widely through the continent during a period of globally warmer temperatures. Their life ways and subsistence patterns, therefore, would have been very different.”
