It’s History

Deep beneath the bustling streets of Detroit lies a subterranean world that many residents don't even know exists. For over a century, a massive network of salt mines has expanded into a 100-mile labyrinth, creating what many call a Secret City 1,000 feet below the surface.

In this documentary, we explore the industrial history of the Detroit Salt Mine, from its discovery in the 1800s to its role in the first-ever road salting project. You will learn how a 400-million-year-old inland sea became the foundation for a massive underground infrastructure featuring 60-foot-wide causeways and towering salt pillars.

In the heart of Chicago, a towering Art Deco masterpiece stands as a monument to two completely opposite Americas. Originally conceived as a pristine shrine to "purity and cleanliness" for a global soap empire, this landmark eventually became the headquarters for one of the most controversial counterculture brands in history.

In this episode, we explore the dramatic transformation of 919 North Michigan Avenue. From its "shadowless" architectural engineering and the world's most powerful aviation beacon to its mid-century rebirth as an adult wonderland, we uncover the secrets of the executive penthouse and the cultural war it sparked between Chicago's traditionalists and the era of Hugh Hefner.

In the late 1970s, when McDonald's sought to conquer the lucrative St. Louis waterfront, they initially pursued a location inside the Gateway Arch itself. Rejected by the National Park Service, the corporation pivoted its strategy, undertaking a monumental challenge: constructing one of the world's first floating fast-food vessels on the temperamental Mississippi River.

This 700-ton cement barge, masquerading as an ornate 19th-century paddle wheeler, became the center of a strange corporate battle against both fierce local opposition and the river’s brutal currents. Witness how this colossal venture survived a legendary rivalry with a Burger King complex, only to succumb to the unforgiving elements and the smell of deep-fryer grease.

Deep beneath the hills of Central Texas lies a network of reinforced‑concrete tunnels built during the Cold War to store and maintain America’s nuclear weapons. Known as Killeen Base (later incorporated into West Fort Hood), the heavily guarded facility featured blast doors, underground storage rooms, and structures designed to absorb the shock of a nuclear attack.

Covers how 25 rural communities were displaced to make way for the installation, why German prisoners of war worked on nearby Texas farms, and Elvis Presley’s six months of training at Fort Hood. Also explores the underground complex’s engineering, its Cold War nuclear mission, and its modern use for military training.

For centuries the Chain O' Lakes shaped the region's history. Originating as glacial kettle lakes used by Native American tribes, they became an industrial lifeline in the 19th century—supplying Chicago’s packer districts with ice and providing millions of tons of gravel for the railroad boom. Later, the lakes hosted flower tours (often misrepresenting common lotus blooms), served as a sanctuary for Al Capone and his Outfit during Prohibition, and evolved into a modern racing ground. #ChicagosHistory #GreatLakes #ProhibitionEra
