The Tri-Cities, or Tri-City area, is a vernacular region that is situated between the large cities of Aurora and Elgin, Illinois, and encompasses the cities of Batavia, Geneva, and St. Charles. A "vernacular region" is a distinctive area where the inhabitants collectively consider themselves interconnected by a shared history, mutual interests, and a common identity. Such regions are "intellectual inventions" and a form of shorthand to identify things, people, and places. Vernacular regions reflect a "sense of place," but rarely coincide with established jurisdictional borders.The Tri-City area is primarily located in Kane County, though Batavia and St. Charles include parcels in DuPage County. The three communities are often grouped together due to their shared history, close proximity on the Fox River, relative socioeconomic condition, and similar population sizes. They are among the oldest in Kane County as well as the state.

Batavia Township is in Kane County, Illinois. It is divided by the Fox River. As of the 2010 census, its population was 35,221 and it contained 12,892 housing units. The western part of the United States Department of Energy's Fermilab is at the township's eastern edge (formerly in the village of Weston), although most of the facility is in neighboring Winfield Township in DuPage County.

MicroBooNE is a liquid argon time projection chamber (LArTPC) at Fermilab in Batavia, Illinois. It is located in the Booster Neutrino Beam (BNB) beamline where neutrinos are produced by colliding protons from Fermilab's booster-accelerator on a beryllium target; this produces many short-lived particles (mainly charged pions) that decay into neutrinos. The neutrinos pass through solid ground (to filter out particles that are not neutrinos from the beam), through another experiment called ANNIE, then solid ground, then through the Short Baseline Near Detector (SBND, in construction, expected to begin operation 2023), then ground again before it arrives at the MicroBooNE detector 470 meters downrange from the target. After MicroBooNE the neutrinos continue to the MiniBooNE detector and to the ICARUS detector. MicroBooNE is also exposed to the neutrino beam from the Main Injector (NuMI) which enter the detector at a different angle. MicroBooNE's two main physics goals are to investigate the MiniBooNE low-energy excess and neutrino-argon cross sections. As part of the Short Baseline Neutrino program (SBN), it will be one of a series of neutrino detectors along with the new Short-Baseline Near Detector (SBND) and moved ICARUS detector. MicroBooNE was filled with argon in July 2015 and began data taking. The collaboration announced that they had found evidence of the first neutrino interactions in the detector in November 2015. MicroBooNE collected five years of physics data, ending its run in 2021 as the longest continually operating liquid argon time projection chamber to date.In October 2021 the results of the first three years of operation were reported. Analyses examined the MiniBooNE low-energy excess, one under a single photon hypothesis and under an electron hypothesis. No evidence for either of these explanations was found within MicroBooNE's sensitivity, which is set by the statistics and systematic uncertainty. The Fermilab press release accompanying the results claimed that the electron hypothesis test dealt "a blow to a theoretical particle known as the sterile neutrino." However, the accompanying commentary to the MicroBooNE papers, when they were published in Physical Review Letters, was entitled "Neutrino Mystery Endures." The full parameter space of sterile neutrino models hinted at by MiniBooNE and other data remains still under investigation.

MiniBooNE is a Cherenkov detector experiment at Fermilab designed to observe neutrino oscillations (BooNE is an acronym for the Booster Neutrino Experiment). A neutrino beam consisting primarily of muon neutrinos is directed at a detector filled with 800 tons of mineral oil (ultrarefined methylene compounds) and lined with 1,280 photomultiplier tubes. An excess of electron neutrino events in the detector would support the neutrino oscillation interpretation of the LSND (Liquid Scintillator Neutrino Detector) result. MiniBooNE started collecting data in 2002 and was still running in 2017. In May 2018, physicists of the MiniBooNE experiment reported a possible signal indicating the existence of sterile neutrinos.

Main Injector Experiment for ν-A, or MINERνA, is a neutrino scattering experiment which uses the NuMI beamline at Fermilab. MINERνA seeks to measure low energy neutrino interactions both in support of neutrino oscillation experiments and also to study the strong dynamics of the nucleon and nucleus that affect these interactions.

The Judge Isaac Wilson House is a historic residence in Batavia, Illinois. It was the home of Isaac Wilson, a former Congressman who moved to the Batavia region and later named the settlement. It was added to the National Register of Historic Places in 1985.

C.W. Shumway & Sons was a foundry operational in Batavia, Illinois from 1872 to 2002. It produced metal castings for various industrial uses and for awards, including the Emmy Award, Academy Awards, and the Vince Lombardi Trophy. The company was closed in 2002 due to changing market demands. At the time of its closure, it was one of the oldest foundries in the United States.

The Loyal Order of Moose is a fraternal and service organization founded in 1888 and headquartered in Mooseheart, Illinois. Moose International supports the operation of Mooseheart Child City & School, a 1,023-acre (414 ha) community for children and teens in need, located 40 miles (64 km) west of Chicago; and Moosehaven, a 63-acre (25 ha) retirement community for its members near Jacksonville, Florida. Additionally, the Moose organization conducts numerous sports and recreational programs, in local Lodge/Chapter facilities called either Moose Family Centers or Activity Centers, in the majority of 44 State and Provincial Associations, and on a fraternity-wide basis. There is also a Loyal Order of Moose in Britain. These organizations together make up the Moose International.

The Eastside Community Center, formerly the Catholic Holy Cross Church, is an historic building in Batavia, Illinois. It was built in 1897 to serve the Holy Cross congregation of Batavia, many of whom were Irish immigrants who came to work in local quarries. The building operated as a church until the 1990s, when the property was transferred to the Batavia Park District. It was added to the National Register of Historic Places in 1999.

Mooseheart, located in Kane County, Illinois, is an unincorporated community and a home for children administered by the Loyal Order of Moose. Also known as the City of Children, the community is featured as a 1949 episode of Metro-Goldwyn-Mayer's short film series Passing Parade, which was written and narrated by John Nesbitt. In 2013, Mooseheart celebrated its 100th anniversary with a rededication ceremony, public tours, fireworks, and other festivities.Like Moose Lodges, Mooseheart was originally only open to Caucasians. The facility was created to be a home for the widows and the children of members of the Loyal Order of Moose. Later, any child who had a family member who was a member of the Moose could be admitted. In 1994, admission policies were changed to allow any child in need to apply for admission, regardless of the family's affiliation or lack thereof with the Moose.In the 1950s, a pediatrician conducting a longitudinal study of children's growth at Mooseheart recalled there was tension since he felt that the board of directors was conducting the study to prove the superiority of the white race. By the 1990s, Mooseheart was open to children of all races and predominantly enrolled minority children.In 1994, four Mooseheart employees were convicted of sexually abusing children. Two years later, a Mooseheart employee was convicted of possession of child pornography.

Batavia () is a city mainly in Kane County and partly in DuPage County in the U.S. state of Illinois. Located in the Chicago metropolitan area, it was founded in 1833 and is the oldest city in Kane County. Per the 2020 census, the population was 26,098.During the latter part of the 19th century, Batavia, home to six American-style windmill manufacturing companies, became known as "The Windmill City." Fermi National Accelerator Laboratory, a federal government-sponsored high-energy physics laboratory, where both the bottom quark and the top quark were first detected, is located just east of the city limits. Batavia is part of a vernacular region known as the Tri-City area, along with St. Charles and Geneva, all western suburbs of similar size and relative socioeconomic condition.

The Batavia Institute is a Registered Historic Place in Batavia, Illinois, US.
