In the early 20th century, coal tycoon, Francis Peabody, commissioned a country home west of Chicago. After Francis died, his heirs sold the estate to the Franciscans. The Franciscans used the mansion as a retreat house. By the early 1990s, the Franciscans no long wanted to maintain this retreat house. They sold some of the Mayslake acreage to a developer. They sold the remainder of the property, including the mansion, to the Forest Preserve District of DuPage County.
The Mayslake Peabody Estate is on the U.S. National Register of Historic Places. Mayslake Hall’s architectural style is “Tudor Revival”. The estate covers a total of 87 acres. The nearest town is Oak Brook, Illinois.
