The Western Open was a professional golf tournament in the United States, for most of its history an event on the PGA Tour. The tournament's founding in 1899 actually pre-dated the start of the Tour, which is generally dated from 1916, the year the PGA of America was founded. The Western Open, organized by the Western Golf Association, was first played in September 1899 at the Glen View Club in Golf, Illinois the week preceding the U.S. Open. At the time of its final edition in 2006, it was the third-oldest active PGA Tour tournament, after The Open (1860) and U.S. Open (1895). The tournament was held a total of 103 times over the course of 108 years. The event was not held in 1900, 1918 (World War I), and 1943–45 (World War II). Players from the U.S. won the tournament 77 times, followed by Scotland with fifteen wins. Walter Hagen had the most victories with five, and seventeen others won the event at least twice. The champions' list includes two amateurs: Chick Evans in 1910 and Scott Verplank in 1985. Beginning in 2007, the Western Open was renamed the BMW Championship, the penultimate event of the FedEx Cup playoff series. Played with the PGA Tour's point system as the sole qualification standard, it is no longer open to amateurs. Title sponsorship was introduced in 1987, and included Beatrice, Centel, Sprint, Motorola, Advil, Golf Digest, and Cialis.

The Lemont Central Grade School is a former school building at 410 McCarthy Road in Lemont, Illinois. The school was built in 1869 to replace Lemont's first school, which opened in 1836 when the area was still largely rural. Locally quarried limestone was used to construct the school; at the time, limestone production was one of the city's main industries. Architect John Barnes of Joliet designed the Victorian building. As the city's population grew considerably during the construction of the Chicago Sanitary and Ship Canal in the 1890s, an annex was placed on the school in 1896 to accommodate additional students. The school operated until building safety issues forced its closure in 1974; at the time, it was the oldest continuously operating school in the state. The building has since been converted to condominiums.The building was added to the National Register of Historic Places on March 7, 1975.

The Lemont Downtown Historic District is a commercial historic district encompassing 14 city blocks in downtown Lemont, Illinois. The district has served as the village's downtown since the 1850s, when the newly opened Illinois & Michigan Canal and subsequent limestone quarrying in the area sparked a local economic boom. It expanded through the late nineteenth and early twentieth centuries as new railroads and the Chicago Sanitary and Ship Canal brought residents and business opportunities to the village. The commercial buildings in the district exhibit a variety of common building types seen between 1850 and 1950; one-part, two-part, gable-front, and false-front buildings are all present, and their designs feature Italianate, Commercial, and revival style architecture. The district also includes several of Lemont's government buildings, including its village hall and post office.The district was added to the National Register of Historic Places on September 6, 2016.

The Chicago Area Waterway System (CAWS) is a complex of natural and artificial waterways extending through much of the Chicago metropolitan area, covering approximately 87 miles altogether. It straddles the Chicago Portage and is the sole navigable inland link between the Great Lakes and the Mississippi River and makes up the northern end of the Illinois Waterway.The CAWS includes various branches of the Chicago and Calumet Rivers, as well as other channels such as the North Shore Channel, Cal-Sag Channel, and Chicago Sanitary & Ship Canal. The CAWS ends near the Lockport Navigational Pool, the highest elevated of the eight pools of the Illinois Waterway. There are three major locks within the CAWS, operated by the Army Corps of Engineers: the Chicago Harbor Lock, the Lockport Lock & Dam, and the T.J. O'Brien Lock and Dam.Artificial waterways connecting the Mississippi and Great Lakes systems via the Chicago area, over the Chicago Portage, began with the I&M Canal in 1848. The CAWS as it exists today began to take shape in 1900, with the construction of the Chicago Sanitary & Ship Canal to reverse the flow of the Chicago River (and eventually the Calumet River), which previously flowed into Lake Michigan, so as to instead flow toward the Mississippi River, thus carrying sewage away from the City of Chicago. Thereafter, additional artificial waterways were built that became part of the CAWS, such as the North Shore Channel, which runs inland from Wilmette to the Chicago River and was constructed in 1910, and the Cal Sag Channel, which provides a direct path from the Calumet River to the Illinois Waterway and was finished in 1922.In the 21st century, a focus of concern around the CAWS has been its potential role as a corridor for Asian carp to enter Lake Michigan. Suits in district court and before the United States Supreme Court have been unable to obtain an injunction requiring the connection between the CAWS and the Mississippi drainage to be closed.

The Track Imaging Cherenkov Experiment (TrICE) is a ground-based cosmic ray telescope located at Argonne National Laboratory near Chicago, IL. The telescope, which contains a Fresnel lens, eight spherical mirrors, and a camera with 16 multianode photomultiplier tubes, uses the atmospheric Cherenkov imaging technique to detect Cherenkov radiation produced when cosmic rays interact with particles in the Earth's atmosphere. The telescope is primarily a research and development tool for improving photomultiplier tube cameras and electronic systems for future gamma and cosmic ray telescopes. It is also used to study the energy and composition of cosmic rays in the TeV–PeV range, and the collaboration is currently conducting pioneering work in detecting direct Cherenkov signals from cosmic rays.
