February 14, 1929: Clark Street in Lincoln Park echoes with the thunder of machine guns
Dive into the heart of Chicago, 1929, and relive one of the bloodiest gangland massacres in American organized crime history.
Step into the shoes of a private detective newly arrived in Chicago, tasked with uncovering the truth behind the St. Valentine's Day Massacre, an event that shook all of Illinois. Your investigation begins at the Lincoln Park Conservatory, the starting point of this 1.5 km route that will lead you to the key locations of the tragedy. At each stop, open your phone: augmented reality clues appear on facades, commemorative plaques, and remnants of the past. A fake police car materializes where Bugs Moran narrowly escaped death, vintage newspaper articles overlay the walls of the Chicago History Museum, and the shadows of Capone's gangsters whisper their secrets. In approximately 165 minutes, at your own pace, you trace your own path through Roaring Twenties Chicago, the one from history books intertwined with urban legends. More than an outdoor escape game: an interactive tour immersed in 200 years of history, with anecdotes revealed at each stop and confidential sites that classic guides often overlook.

The story that haunts this land
Your quest begins at the Lincoln Park Conservatory, a complex of Victorian greenhouses built between 1890 and 1895, covering 0.8 hectares under glass. This location, the starting point of your journey within the Lincoln Park Historic District, houses four thematic greenhouses: tropical, fern, palm, and show house, all open daily and free of charge. It is here, amidst the lush ambiance of these gardens, that you receive your initial instructions to unravel the plot of February 14, 1929, targeting Bugs Moran's gang in Chicago's Lincoln Park neighborhood.
The first key site of your investigation leads you to 2122 North Clark Street, the exact location of the St. Valentine's Day Massacre. Here, on February 14, 1929, seven members of Bugs Moran's gang were executed by Capone's men, including Fred 'Killer' Burke and John 'Shotgun' Ziegler disguised as police officers, in the S-M-C Cartage garage. The building was demolished in 1967, leaving today only a parking lot near the Margaret Day Blake Apartments. It was in these very places that Bugs Moran, having spotted a fake police car, escaped the massacre by taking refuge in a café, thus changing the course of Chicago's history.
Continuing your itinerary in Chicago, you reach the Chicago History Museum, founded in 1868 and renamed in 1932. Located at 1601 Clark St, just 0.5 km from the starting point, this 72-meter long neoclassical building houses the largest collection of Chicago history, the Starr Library. Its collection includes artifacts from the St. Valentine's Day Massacre and the Capone era, essential for contextualizing your investigation. The museum, a Chicago Landmark and listed on the National Register of Historic Places, offers insight into Illinois' heritage far beyond the 1929 events.
Your journey also takes you to St. Michael Church, a Catholic church built in 1869 in Old Town, near Clark Street. Its 91-meter tower is the only major structure to have survived the Great Chicago Fire of 1871. Located at 1633 N Cleveland Ave, this church testifies to the city's resilience and its deep connection to the history of the neighborhood. Although not directly related to the massacre, its presence in this historic sector of Chicago highlights the contrast between faith and the violence that marked this period.
Finally, your investigation leads you to the Lincoln Park Zoo, the oldest free zoo in the USA, opened in 1868 and spanning 14 hectares with over 1,200 animals. Adjacent to the Conservatory, the zoo, with its Lion House dating from 1893, is a historic site funded by the Chicago Park District. The Ulysses S. Grant Monument, a 9-meter high equestrian statue erected in 1891 near the Conservatory, commemorates President Grant (1822-1885). By visiting these places, you gain a better understanding of Chicago at the time, a melting pot of modernity and tensions, where Al Capone's shadow loomed over Illinois' heritage. This interactive walking tour in Chicago offers a unique perspective on the past, revealing the layers of history that shaped this iconic city.
