An old lakeshore
About 14,000 years ago, the land under LaGrange sat on the western shore of Lake Chicago, the glacial lake that came before Lake Michigan. Bluff Avenue, on the east side of the village, follows that old shoreline.
Settlers and the railroad
Settlers came in the 1830s on land grants. Samuel Vial received his in 1834, and Robert Leitch built his cabin near what’s now Ogden Avenue. The Chicago, Burlington and Quincy Railroad gave the area its first rail link to Chicago in 1864, and the stop was a milk stop called Hazel Glen.
Cossitt’s village
Franklin D. Cossitt bought Leitch’s land in 1870 and set out to build an ideal suburban village. He laid out streets, planted trees, donated land for churches and schools, and built homes for sale. His investment in the Fifth Avenue station, now LaGrange Road, helped the town grow. The village grew from just over 500 residents to nearly 4,000 in the 1880s and 1890s, and by 1890 it was one of the largest towns between Chicago and Aurora.
Downtown
Some downtown buildings date from the 1890s, when shops and businesses began to flourish around the station. For many years downtown LaGrange was one of the busiest shopping areas outside the Chicago Loop, and Village Hall still anchors it today.
Keeping the history
Residents formed the La Grange Area Historical Society at the public library in 1972. The village’s historic district joined the National Register in 1979, and it includes more than 1,000 buildings, a few of them designed by Frank Lloyd Wright.
