The Dark History Beneath Downtown Phoenix

Most people think downtown Phoenix is all new development. Luxury apartments. Sports arenas. Cocktail bars. Rooftop lounges. But beneath modern Phoenix lies a much darker history — one filled with buried graves, forgotten neighborhoods, ancient civilizations, hidden tunnels, and pieces of the city that were quite literally built over. And every once in a while, construction crews accidentally uncover it.

Before Phoenix, There Were the Hohokam

Long before Phoenix existed, the Valley was home to the Hohokam people, who created one of the most advanced canal systems in North America. Their canals became the foundation for modern Phoenix irrigation.

But the Hohokam didn’t just leave behind canals.Over the years, construction projects throughout Phoenix have uncovered Hohokam artifacts, pottery, settlements, and burial sites buried beneath the city. One discovery reportedly happened during development near the downtown Fry’s area, where excavation work revealed Hohokam graves beneath the surface. Meaning modern Phoenix wasn’t just built near history. It was built directly on top of it.

The Forgotten Graves Beneath Phoenix

As Phoenix grew in the late 1800s, cemeteries began forming around the edges of town.

Many early pioneers, railroad workers, immigrants, tuberculosis victims, children, drifters, and even vigilantes were buried in or near what would later become downtown Phoenix.

Some graves were eventually relocated to Pioneer & Military Memorial Park. Others weren’t.

In 2012, construction crews building the new Maricopa County Sheriff’s Office headquarters uncovered human remains and old coffins beneath the property. Historians later confirmed the site had once been part of one of Phoenix’s earliest graveyards. Some graves were marked. Many were not.

Which means parts of downtown Phoenix may still contain forgotten burials beneath government buildings, streets, parking lots, and warehouses. That realization unsettled a lot of locals.

Because it confirmed something Phoenix historians had suspected for years: Not everyone was moved.

The Chinatown Phoenix Buried

One of the most overlooked parts of downtown Phoenix history is Chinatown.

In the late 1800s, Phoenix’s Chinese immigrant community built businesses, restaurants, laundries, grocery stores, and social halls downtown despite intense discrimination.

Eventually, Phoenix pushed Chinatown farther south, away from the growing center of the city.

The second Chinatown became known for hidden tunnels, gambling halls, and underground opium dens beneath parts of downtown Phoenix.

But over time, the neighborhood faded away as Phoenix redeveloped the area. And then came America West Arena. During construction of the arena in the early 1990s, crews reportedly uncovered remnants connected to old Chinatown beneath the site — including underground spaces tied to the district’s past.

Today, thousands of people attend concerts and basketball games there without realizing they’re standing on top of one of Phoenix’s forgotten communities.

The City Beneath the City

Downtown Phoenix may look modern, but beneath the streets lies a buried history filled with forgotten graves, lost neighborhoods, ancient civilizations, and stories the city tried to leave behind.
