The River Road-Mead Avenue Historic District lies between two centers of maritime commerce at the lower and upper landings on the Mianus River and played an important role in the early development of the Town of Greenwich. It was once part of William H. Mead's farm and was subdivided by Mead into one-half acre lots in 1835. The area developed slowly up through the Civil War, but between 1870 and 1910 grew into the most prestigious neighborhood in the village of Cos Cob and remains today as one of the best examples of pre-World War I, upper-middle class housing in Greenwich. Its nineteenth-century homes and carriage houses, later adapted by new owners into residences, preserve a significant variety of architectural styles including Greek Revival, Italianate and Second Empire, while its early twentieth century homes showcase notable examples of Colonial Revival and shingle styles.
The waterfront side of River Road today is now a mix of commercial, recreational and residential use, and the entire area has thrived through the centuries to become the vibrant historic community we know today.
