Stunning mansion for sale in Illinois has chic underground tunnel. See where it leads
A home with an unusual hidden feature that you don’t see every day has landed on the real estate market in Alton, Illinois, for $8.45 million.
The massive nine-bedroom, 9.5-plus-bathroom megamansion has an enchanting allure throughout the interior and is graced with style. Called the Olin Mansion (after the home’s architect, John Olin), the sophisticated home has been a popular meeting place for certain A-listers, Realtor reports.
“The family business was gunpowder and chemical manufacturing,” says listing agent Don Brown told Realtor. “Multiple U.S. presidents and celebrities are rumored to have visited the residence.”
