Late last week our team photographed in the eastern end of O’Fallon on Green Lea Place, Harris Avenue and Clay Avenue. This pocket of the neighborhood is in the Third Ward of the city,while the rest lies in the Twenty-First. As with much of the rest of the center of O’Fallon, the development here is marked by a diversity of forms, periods and materials. There is a notable concentration of frame buildings here. Harrison School at Fair and Green Lea Place, vacant and for sale after an aborted rehab effort, is an anchor.
