About this map

Fairview Heights and O'Fallon anchor this suburban and industrial landscape as it appeared in the early 21st century. The map reveals the intricate growth of eastern Saint Clair County, where traditional settlements like Swansea and Shiloh have expanded toward the major transport corridors of Central Park Dr and Frank Scott Pkwy E. This modern survey is particularly useful for locating community landmarks and educational institutions, such as the Southwestern Illinois College - Belleville Campus.

Genealogists and local historians will find significant value in the preservation of several historic burial grounds across the area. From the Old Saint Clair County Cem in the west to Mount Calvary Cem and Saint Johns Orphanage Cem near the center, the map tracks the intersection of established heritage sites with newer residential developments like Crossroads and Glenview. The natural drainage of Richland Cr and Rock Spring Br provides a consistent physical framework amidst the rapid urbanization of the region.
