Opened in 1916 as both a shipping dock and public entertainment space, Navy Pier has evolved into one of the country’s most visited tourist destinations. Originally named “Municipal Pier,” plans for its construction were included in Daniel Burnham’s Plan of Chicago, which laid out detailed infrastructure and public works plans for the growing city.

The pier was integral during both world wars, housing soldiers in World War I and training an estimated 60,000 military personnel during World War II. The University of Illinois established a campus on the pier in the 1940s until building their permanent home in Chicago’s Near West Side neighborhood in the mid-1960s.

After several decades serving as a public event space, a major renovation in the early 1990s led to the development of several restaurants, the Chicago Shakespeare Theater and the infamous Ferris wheel. Over the weekend, the Ferris wheel hosted its last visitor, as plans to replace it with a taller Ferris wheel to open in mid-summer 2016 were announced. The current Ferris wheel has hosted more than 10 million visitors in the 20 years it has been in operation.

Zachary, a baby western lowland gorilla, was unveiled this week at Brookfield Zoo in suburban Chicago. The baby gorilla, born earlier this week, will spend the next four to six months in the arms of his mother, 11 year-old Kamba. After that, he will spend most of his days on Kamba’s back until learning to move on his own.

Zachary joins the more than 300 western lowland gorillas living in zoos across North America. Native to West Africa, the gorilla remains an endangered species due to hunting, habitat destruction and disease.

The Modoc Rock Shelter, located near the Missouri border in Southern Illinois, is a cut-out section of cliff overlooking the Mississippi River valley. The cliff was formed by ice age floods that carved through the land thousands of years ago.

Archaeological discoveries by Irwin Peithmann in the 1950s found artifacts in the shelter that proved groups of people had been there as far back as 9,000 years ago. From Peithmann’s discoveries, it has been concluded that Native American hunters used the shelter as a safe area away from the elements. His excavations also have concluded different groups used the site as a long-term base camp around 6,000 years ago, and small hunting parties inhabited the area around 4,000 years ago. Hammer stones, bone awls and projectile points are just a few of the many discoveries found at the site.  

It was declared a National Historic Landmark in 1961.
