A Rodent Left An Imprint in a Chicago Sidewalk, Then It Became a Tourist Attraction

For decades, people walking along West Roscoe Street in Chicago passed an oddly shaped depression in the sidewalk without giving it much thought. The imprint looked remarkably like the flattened body of a small rodent, complete with outstretched legs and the suggestion of a tail. Neighbors knew it was there, children noticed it, and at least one local softball team had already adopted the creature as an unofficial mascot. Then, in January 2024, a photograph of the sidewalk went viral and transformed an ordinary residential block into one of Chicago's strangest tourist attractions. The spot became known as the Chicago Rat Hole. It was located in front of 1918 W. Roscoe Street in the Roscoe Village neighborhood, between Wolcott and Damen avenues. The indentation appeared to preserve the outline of an animal that had somehow landed in concrete while the sidewalk was still wet. Its body was pressed flat against the surface, with four limbs stretched outward in a pose that made the imprint look almost cartoonishly perfect. Chicago artist and comedian Winslow Dumaine brought the obscure neighborhood oddity to a much larger audience on January 6, 2024, when he posted a photograph after making what he jokingly described as a pilgrimage to the Chicago Rat Hole. Millions of people saw the image. Within days, strangers were arriving on Roscoe Street specifically to look down at a small depression in the pavement. What happened afterward turned the sidewalk into something resembling a miniature shrine. Visitors began dropping coins into the imprint. Others left flowers, candles, food, toys, cigarettes, alcohol, handwritten notes and small objects. People posed for photographs beside it. Someone placed a tiny cheese offering nearby. Couples incorporated the Rat Hole into dates, visitors traveled from outside Chicago to see it, and the otherwise unremarkable patch of concrete became a destination in its own right. At least one couple even held a wedding ceremony at the site. The sudden fame was amusing to many Chicagoans, but residents of the block experienced a different side of the phenomenon. Crowds appeared from morning until late at night. Some visitors left trash behind, while others brought alcohol or food that neighbors worried could attract actual rats. The unusual tourist attraction was sitting immediately outside people's homes rather than in a park or commercial district designed to accommodate visitors. There was also a growing problem with the name. The Chicago Rat Hole probably was not made by a rat. Longtime residents told local reporters that they believed the animal responsible was a squirrel. Trees once stood over the sidewalk, and the shape of the imprint, particularly the body and limbs, looked more consistent with a squirrel that had fallen from above than a rat walking across fresh concrete. The debate continued long after the Rat Hole became famous. Then researchers decided to approach the mystery as an actual zoological question. A scientific analysis published in 2025 compared the imprint's anatomy and proportions with rats and squirrels. The researchers concluded that the animal was much more likely to have been a squirrel. In other words, one of Chicago's most famous rats was probably never a rat at all. Exactly how the imprint formed remains uncertain. The simplest explanation is that the animal fell or landed on freshly poured concrete before it hardened. Whether the creature died there, escaped after creating the impression, or was removed by someone is not firmly documented. Stories from the neighborhood have accumulated over the years, but the sidewalk itself preserved only the shape, not a reliable account of what happened. The age of the imprint is also somewhat uncertain. Residents said it had existed for decades, with estimates commonly placing its creation roughly 20 to 30 years before it became famous. One neighborhood story dates the event to the early 1990s. Whatever the exact year, the Rat Hole was already an old local curiosity by the time the internet discovered it in 2024. Its viral fame almost destroyed it. On January 19, visitors discovered that someone had poured a plaster-like substance into the indentation, completely filling the famous shape. The apparent attempt to erase the Rat Hole produced exactly the opposite reaction. People gathered at the sidewalk and carefully removed the material, digging and scraping until the animal-shaped impression reappeared. For supporters, rescuing the Rat Hole became a small act of Chicago civic pride. The situation was becoming increasingly difficult for the residents who actually lived beside it, however. The sidewalk had become crowded, damaged and filled with objects left by visitors. The city eventually decided that the concrete needed to be replaced. On April 24, 2024, Chicago Department of Transportation crews arrived and cut out the sidewalk slab containing the Rat Hole. For a moment, it appeared that Chicago's strangest new landmark had vanished almost as quickly as it became famous. Fresh concrete replaced the old section of sidewalk, leaving no animal-shaped depression for tourists to visit. But the city did not destroy it. Workers carefully removed the slab containing the imprint intact and placed it into storage. The city said the piece had been preserved while officials considered what to do with it. Instead of being jackhammered into rubble, the Rat Hole effectively became an artifact. Its removal ended an unusual chapter for the residents of Roscoe Street. The stream of visitors diminished because there was no longer anything unusual embedded in the sidewalk outside 1918 W. Roscoe Street. What remained was simply a repaired section of pavement and the memory of several months when tourists lined up to photograph the outline of a dead, or possibly merely unlucky, squirrel. The story continued anyway. The Rat Hole inspired merchandise, artwork and even a music festival. Its image became instantly recognizable to many Chicagoans despite having no official historical significance, architectural importance or connection to a famous person. It became famous almost entirely because people collectively decided that an animal-shaped dent in concrete was worth celebrating. That may be the most Chicago part of the story. The city is filled with monumental architecture, museums, skyscrapers and internationally famous landmarks, but for several months in 2024, visitors were making special trips to a residential sidewalk to leave coins for what they thought was a rat. Today, anyone traveling to the original coordinates near 1918 W. Roscoe Street will not find the Rat Hole itself. The sidewalk slab has been removed, and the original imprint is no longer sitting outside the home where it spent decades unnoticed. Yet the slab still exists. And thanks to later research, Chicago's legendary Rat Hole may eventually be remembered by an even stranger description: a world-famous rat-shaped hole that was probably made by a squirrel.
