Rising 192 meters above the Mississippi River, the Gateway Arch is one of the most striking monuments in the United States. A stainless-steel curve that turned pure geometry into national poetry.

In this episode, we'll discover the story behind Eero Saarinen’s masterpiece: from the ambitious vision of St. Louis in the 1930s, to the dramatic father-and-son design competition, to the decades of delays, protests, and technical challenges that nearly stopped it from being built.

You’ll hear about the hidden engineers who made it possible, the civil rights activists who turned it into a stage for protest, and the quiet genius who invented its one-of-a-kind tram system.

A story of ambition, time, and beauty.
