Leaning Tower of Niles
The Leaning Tower is a perennial stop for Roadsiders in the Chicago area, and only 15 minutes northeast of O'Hare Intl. Airport (and 10 minutes from the World's First Franchised McDonald's in Des Plaines). The Leaning Tower of Niles is, of course, a replica of Italy's Leaning Tower of Pisa. It is roughly half-sized -- 94 feet, vs. the authentic's 177 feet, and leans about 7'4" off plum (vs. Pisa's 15 foot tilt). But that hardly matters when you're standing across the street taking a picture. And the savings in overseas airfare and reduced risk of injury is worth considering.
America's Leaning Tower was built in 1934 (600 years after the original), and for many years has stood in front of the Tower YMCA. It was a utility tower, made from steel, concrete and precast stone, designed to store water. A plaque at its base says it was built to honor the outstanding scientist Galileo Galilei.
The plaza around the tower was renovated in the late 1990s, adding a fountain and other touches.
