Walk the length of Denver's 16th Street Mall today and you'll pass chain restaurants, hotel lobbies, coffee shops, street performers, and the constant swoosh of free mall ride buses. It's pleasant and busy — Denver's version of a downtown promenade. But the street underneath has a history that predates Colorado statehood, and the story of how it became what it is today reflects everything about how the American West built itself up and then, in places, tore itself apart to start again.
Before the Mall: Holladay Street and the Wild Foundation
In the 1860s, this stretch was called Holladay Street, and it was the commercial and entertainment center of a booming frontier town. Denver was founded in 1858 at the confluence of Cherry Creek and the South Platte River, initially as a mining supply depot for the Pikes Peak Gold Rush. It grew fast and rough.
Holladay Street was where the saloons, gambling halls, and brothels operated — an open-air economy of frontier vice that would have been familiar to anyone who'd spent time in Tombstone or Deadwood. The street was renamed Market Street in 1888, partly to distance the city's image from its rougher origins as Denver tried to present itself as a serious metropolis rather than a frontier outpost.
The Golden Age: 16th Street as Commercial Spine
By the late 19th and early 20th centuries, 16th Street had become Denver's premier commercial corridor. Department stores, banks, theaters, and hotels lined both sides. The Daniels & Fisher Tower — built in 1910 and still standing today — was the tallest building west of the Mississippi when it was constructed, modeled on the Campanile di San Marco in Venice. The street was the address for Denver's retail and financial ambition.
The Brown Palace Hotel, opened 1892 just off 17th Street, hosted every sitting US president from Theodore Roosevelt onward and was the social center of Colorado's business world. The streetcar lines that ran 16th Street connected the downtown core to neighborhoods spreading outward as Denver grew into a real city.
Decline: The Suburban Shift
The post-World War II American story played out in Denver as it did in virtually every American downtown: suburban malls, highways, and the mass adoption of the automobile pulled investment and population away from the urban core. By the 1970s, 16th Street was struggling. Retail had followed residents to suburban shopping centers. The storefronts that once housed Denver's finest department stores were increasingly vacant or degraded.
The city faced a question that urban planners across America were grappling with: how do you make central downtown worth visiting when the car has made distance irrelevant?
The Mall: 1982 and the Pei Redesign
The answer Denver chose was transformation. In 1982, after years of planning, the 16th Street Mall opened — a mile-long pedestrian and transit mall stretching from Civic Center Park to Union Station, designed by the firm of I.M. Pei (the architect who would later add the glass pyramid to the Louvre). The design featured pink and gray granite pavers laid in a repeating diagonal pattern, mature trees, and a free shuttle bus running the entire length every few minutes.
The mall was an immediate success in terms of foot traffic and has remained the anchor of Denver's downtown ever since. A major renovation completed in 2024 modernized the infrastructure while preserving the Pei design language.
What Survives
The Daniels & Fisher Tower still stands — now a shell incorporated into a modern development, its campanile rising incongruously above newer glass. The Brown Palace Hotel still operates as one of the finest historic hotels in the American West. The atrium lobby, the afternoon tea, and the Sunday brunch are Denver institutions. Union Station at the mall's northern end was restored in 2014 into a world-class transit hub and hotel — arguably the finest adaptive reuse project in Colorado.
The street that was once Holladay, then Market, then the commercial spine of a frontier city is now a pedestrian mall. History is layered underneath the granite pavers — literally, in some cases, since archaeological excavations during construction found artifacts from Denver's earliest years just below the surface.
