Fontbonne University (MO) will close in 2025, a decision that follows years of dwindling enrollment and financial losses at the 100-year-old Clayton-based liberal arts institution. Neighboring Washington University will purchase Fontbonne’s 16-acre campus “in the coming months” as part of a purchase agreement, Fontbonne officials said. A sale price was not disclosed. Washington U, in a statement Monday, said it has no definitive plans for the site, which located just south of its campus.
