Batavia was founded in 1833, and is the oldest city in Kane County, Illinois, with a small portion in DuPage County. During the Industrial Revolution, Batavia became known as ‘The Windmill City’ for being the largest windmill producer of the time. Fermilab, a federal government-sponsored high-energy physics laboratory, where both the bottom quark and top quarks were first detected, is located here. Batavia is part of a Tri-Cities area, along with St. Charles and Geneva. Its population has been increasing, from 23,866 in the 2000 U.S. census, 25,246 in 2003 to 27,502 in the 2008 U.S. Census Bureau census
