The History of Hot Springs in Illinois
During the mid-19th century, Illinois experienced a boom in mineral spring resorts as several springs were discovered with high concentrations of magnesium, sulfur, and other minerals believed to have healing properties. Towns such as Vishnu and the Mineral Springs of Pekin quickly became popular destinations, drawing visitors seeking therapeutic baths, luxury accommodations, and entertainment.
For decades, these hot spring resorts thrived, catering to both locals and tourists. However, as medical advancements replaced traditional mineral therapies, and tourism trends shifted toward urban centers, many of these once-prosperous destinations declined. Economic downturns and the expansion of modern spa facilities further contributed to their closure. Over time, most of Illinois’ hot spring resorts were abandoned, and the once-thriving industry faded into history.
Today, only one hot spring remains in operation—The Original Springs Hotel—continuing the state’s legacy of geothermal bathing. While Illinois no longer has multiple hot spring resorts, a few cold mineral springs still exist, offering visitors a chance to experience the mineral-rich waters that once made Illinois a sought-after wellness destination.
Hot Springs in Illinois – The Original Springs Hotel
Discovered in 1867 by Rudolph Plegge, The Original Springs Hotel is home to Illinois’ only remaining hot mineral spring. While using well water on his property, Plegge noticed its high mineral content corroded his kitchenware. Tests revealed elevated levels of magnesium and sulfur, known for their therapeutic benefits.
Recognizing the spring’s potential, Plegge built a bathhouse, drawing visitors seeking relief from ailments. As mineral spring resorts surged in popularity, his facility thrived. After a devastating fire, the bathhouse was rebuilt and remains operational 150 years later.
Today, The Original Springs Hotel blends historic charm with modern comforts. Guests can soak in mineral-rich waters, stay in onsite accommodations, and enjoy spa treatments and fine dining. The hotel is also a hotspot for paranormal activity, attracting visitors intrigued by its haunted reputation.
