Cuneo Mansion & Gardens in Vernon Hills, Illinois, is a rare glimpse into Lake County’s Gilded Age, blending Italian villa architecture, significant local business history, and a continuing role as a cultural landmark. This estate’s story ties together the rise of regional industry, changing patterns of suburban growth, and modern preservation efforts that keep its legacy alive today.
Origins of an Italian Villa in Lake County
Construction on the mansion began in 1914 and was completed around 1916 as a country estate for utilities magnate Samuel Insull. Insull, an early founder of General Electric and the creator of Commonwealth Edison, chose a then-rural site northwest of Chicago, reflecting the “gentleman farmer” lifestyle popular among wealthy industrialists of the era.
Chicago architect Benjamin Marshall of the Marshall & Fox firm designed the house in an Italian villa or Mediterranean Revival style inspired by country estates in northern Italy, as documented by the Chicago House Museums association at Italian villa or Mediterranean Revival style. The resulting home—set behind an ornate iron fence on what was once a much larger tract of land—stood out dramatically against the surrounding farmland and, later, the emerging suburban landscape.
Architecture and Interior Splendor
The mansion’s architecture is defined by stuccoed walls, red tile roofing, and a layout organized around an interior courtyard. Inside, a central atrium with an arcaded hall, Ionic columns, and a second-floor loggia creates a theatrical sense of space, once covered by a retractable skylight that flooded the house with natural light.
Rooms such as the great hall, formal dining room, and private chapel are richly decorated with European antiques, Renaissance paintings, tapestries, silver, and porcelain collected by the Cuneo family over decades. Details like gilded bathrooms, stained glass windows, and paneling repurposed from a 17th-century ship’s captain’s quarters underline the estate’s emphasis on craftsmanship and display.
Cuneo Family Stewardship
Insull’s utility empire collapsed during the Great Depression, and in 1937 the estate was purchased by Chicago businessman and philanthropist John Cuneo Sr. Cuneo, whose enterprises included the Cuneo Press, National Tea Company, and Hawthorn Mellody Farms Dairy, made the mansion his family home with his wife Julia and their children.
Under the Cuneos, the property became not just a residence but a showcase for art, religious objects, and fine furnishings connected to their Catholic faith and social networks. After Julia Cuneo’s death in 1990, the house transitioned from private residence to public institution, opening as the Cuneo Museum and Gardens in 1991 so visitors could experience the interiors and collections firsthand.
Jens Jensen’s Landscape Legacy
The estate’s grounds are as historically significant as the house. Landscape architect Jens Jensen, known for his prairie-style designs and use of native plants, created the original garden plan for the property.
His design included man-made lakes, a waterfall, a cobblestone bridge, and a council circle intended as a quiet gathering space in the landscape. John Cuneo later reworked many of the garden “rooms” into a more formal, ornamental style while retaining major Jensen features like the water elements and circulation patterns. Today, the grounds—reduced from their original vast acreage but still expansive—offer manicured lawns, sculpture-dotted vistas, and walking paths that contrast with the nearby commercial development along Milwaukee Avenue.
From Private Estate to Public Museum
The Cuneo family created a foundation to ensure the estate’s preservation, and by the early 1990s the mansion and gardens were open for guided tours that highlighted both the art collection and architectural details. Visitors could explore grand entertaining spaces as well as more intimate family rooms, gaining insight into the lifestyle of Chicago’s early- and mid-20th-century elite.
In 2009, the Cuneo Foundation entrusted the mansion, grounds, and art collection to Loyola University Chicago, which assumed stewardship and invested millions of dollars in restoration and event-related upgrades. Under Loyola, the site continued to function as a house museum and also served as a venue for weddings, corporate gatherings, and university functions, extending its role as a community gathering place.
Recent Transitions and Future Use
A major turning point came in the mid-2010s when agreements among Loyola, the Village of Vernon Hills, and Lake County opened the door for the property’s eventual transfer to the village. By late 2025, Vernon Hills had arranged to acquire the mansion and gardens at a nominal cost, with local officials emphasizing community input on future programming and preservation priorities.
Area historians and preservation advocates have highlighted the estate’s importance as a rare surviving example of an Italian Renaissance–style country house in the Chicago region, arguing for continued protection of both the building and its designed landscape. Ideas for the site’s next chapter include operating it as a house museum, hosting educational programs, and carefully balancing public access with conservation.
Cultural Impact and Lasting Legacy
Cuneo Mansion & Gardens stands today as a vivid record of how wealth, industry, and landscape design shaped Lake County during the 20th century. The estate tells overlapping stories: Insull’s role in electrification, the Cuneo family’s influence in printing, retail, and agriculture, and the evolution of Vernon Hills from open countryside to a busy suburban hub surrounding a historic enclave.
As local leaders work out the property’s long-term future, the mansion and gardens continue to embody old-world elegance amid modern development and remain a powerful teaching tool about architecture, art collecting, and regional history. Whether experienced on a guided tour, during a special event, or through community programming, Cuneo’s enduring legacy lies in connecting contemporary residents to the people, spaces, and stories that shaped Lake County’s past.
