The region was platted by William Robbins, the founder of Hinsdale, in 1865. The Chicago, Burlington and Quincy Railroad's passenger station prompted several small businesses to develop across the street. Fifty-eight of the listed buildings were built for commerce, three for government, and nine for transportation. The remaining building is a theater. The shops are densely clustered in orthogonal patterns, and are mostly found on the south side of the railway tracks. The government buildings, including the Village Hall and U.S. Post Office are on the north side.
