History
, a local lawyer, prominent politician and United States Senator from Illinois, founded Elsah in 1853 and offered free lots to anyone who built houses with stone from his quarry. It is believed that he named the village of Elsah after Ailsa Craig, the last outcropping his family saw as they departed Scotland for the United States. By 1861, the village had grown to its current size, as geographic and economic limitations prevented further expansion. Although Elsah has been described as the "New England of the Midwest," the village is not a New England prototype derived from 18th century colonial styles. Rather, the architecture found in Elsah demonstrates 19th century styles and fashions including Greek Revival, Gothic Revival, Mansard, Italianate, Saltbox, and Gambrel. Elsah prospered as the main shipping point for the agricultural goods produced by the farmers of Jersey County. The village's importance diminished with the coming of the railroad, later being revitalized when Principia College was established in the 1930s. Elsah remained mainly a quiet village until the opening of the Great River Road in 1964. Elsah is a community whose homes are privately owned. In 1973, the entire village was placed on the National Register of Historic Places. The Great Flood of 1993 caused significant damage to many of the village's structures. The historic commercial district on LaSalle Street, which extends three blocks inward from the river, consists mainly of stone buildings; all but one of its pre-1861 buildings, including all four of the village's historic taverns, still stand. The other two districts are both located on Mill Street and are primarily residential; the larger one is three blocks long and has an assortment of stone and brick houses, while the smaller section has a single block of Greek Revival homes. Today, Elsah's proximity to bald eagle watching locations make it a popular destination during the fall and winter seasons. Elsah's location on the Sam Vadalabene Bike Trail also makes it a popular stop for bicyclists enjoying the Great River Road in any season.
