Cook County Hospital is a Chicago icon and one of our most fascinating landmarks. Founded in 1857 as a teaching hospital, the institution revolutionized medicine with innovations such as the country’s first medical internship program and the world’s first blood bank. It even had a starring role in The Fugitive! But international renown can’t stop the wear and tear of time, and the original building was eventually vacated in 2002. It’s been empty ever since—until now.
