This week marks 30 years since the Berlin Wall came down. In Illinois, there are two locations where pieces of the wall are on public display. You can see a chunk of the wall at a Chicago CTA station. Or in a more relaxed setting in a peace garden at Eureka College in Woodford County. The college is the alma mater of President Ronald Reagan, who gave the famous directive to Soviet Leader Gorbachev to “tear down this wall.”
