Antioch Community High School, Antioch, or ACHS, is a public four-year high school located in Antioch, Illinois, a far north suburb of Chicago, Illinois, in the United States. It is part of Community High School District 117, which also includes Lakes Community High School.HistoryACHS was built in 1915 at 1133 Main Street, where it has remained since then. Though the original building was renovated in the late 1990s to make room for new facilities, it has undergone numerous additions and a name change throughout its history. ACHS was originally named Antioch Township High School when it was founded in 1915. In February 1926, voters approved $65,000 to build a two-story north wing to the existing high school, which served 184 students at the time. In 1953, the school was improved once again with the addition of a new wing expanding the school further north. The old gym was converted into an auditorium large enough to hold the 382 students enrolled at the time, and new gym was added, in addition to new class rooms and office space. In November 1962, an addition was made to the west of the school. Science labs, a cafeteria, classrooms, and a library blocked the view of the original Antioch Township High School which was renamed Antioch Community High School the following year. In 1972, additions where needed again to house the 1,377 students enrolled. Additions to the north wing added drivers ed. and fine arts facilities, a new gym, lockers, 24 classrooms, and a commons area. But only 26 years later, the school underwent a major renovation to accommodate the population growth in the 1990s. The original building was razed in 1998 to pave the way for extensive remodeling and new additions. A third gymnasium was built in 2004. More than $16 million in renovations have been made since 2003.
