Oak Brook, Illinois

Peabody's Mansion

Tour the grounds of an incredible estate, featuring unparalleled architecture, murmurous monks, and tales of a curious corpse.

Expert docents share the architectural and engineering wonders of this infamous estate along with the legends and lore of the dark woods that surround it.

According to legend, tucked within the dark wooded grounds surrounding the beautiful Tudor Revival Style Peabody Mansion, is a tiny tomb containing preserved body of Francis Stuyvesant Peabody. Countless high-school delinquents have spent evenings wandering the grounds of the Mayslake Estate, dodging a menacing order of silent monks and the tortures they had in store for those unlucky enough to be caught. 

Depsite the grotesque legend, the Peabody Mansion is one of Chicago's most overlooked architectural jewels. Peabody’s Mansion (also known as the Mayslake Estate) was built by Marshal and Fox, the masterminds behind other local landmarks including the Drake, Blackstone, and Edgewater Beach hotels, the Steger building, and much of the South Shore Country Club. After owner Francis Peabody’s death, the mansion was sold to an order of Franciscan monks who added a perfect replica of the Italian Portiuncula Chapel to the grounds.

Transport yourself from the opulent charm of a Gatsby-esque mansion, into a world were history meets horror, and one man’s legacy becomes Chicago’s urban legend.
