Lebanon, Illinois carries the quiet confidence of a town that has seen centuries come and go without losing its sense of place. Roughly 30 minutes east of St. Louis, this small St. Clair County city of about 4,700 residents anchors itself around McKendree University, founded in 1828 as the oldest college in Illinois. The university gives Lebanon a steady intellectual pulse that a town of barely three square miles might not otherwise sustain, drawing students, staff, and cultural programming that keeps the community engaged year-round.
Downtown Lebanon reads like a preserved chapter of 19th-century American architecture, where Gothic, Italianate, Greek Revival, and Queen Anne buildings line the streets alongside the Mermaid House, a landmark that hosted Charles Dickens during his 1842 American tour. The Looking Glass Playhouse and the Hettenhausen Center for the Arts add a performing arts dimension. Scott Air Force Base, just 20 minutes away, adds another significant employment anchor to the area.
The rental market here reflects the town's scale: expect historic single-family homes and modest apartment communities. Renters gain access to the broader St. Louis metro while trading congestion for tree-lined streets, trail access, and a genuinely unhurried way of living.

The GreatSchools Rating helps parents compare schools within a state based on a variety of school quality indicators and provides a helpful picture of how effectively each school serves all of its students. Ratings are on a scale of 1 (below average) to 10 (above average) and can include test scores, college readiness, academic progress, advanced courses, equity, discipline and attendance data. We also advise parents to visit schools, consider other information on school performance and programs, and consider family needs as part of the school selection process.
