The water that fed the oystermen now carries sailboats. In May 1888 a retired Civil War captain named George I. Tyson built a clubhouse on his own waterfront on the eastern shore of Cos Cob Harbor, at the mouth of the Mianus, and founded the Riverside Yacht Club — the second-oldest yacht club in Connecticut and among the oldest in the United States. Its Victorian clubhouse went up the next year, and the club has been racing on Long Island Sound ever since. Sailcloth, brass, and harbor-grey: this is Riverside’s prevailing weather.
What’s with Mianus Neck? Before it was Riverside, this corner of Greenwich was called Mianus Neck — a quiet 17th-century farming-and-oystering village on the lands lying by the Mianus River. The river, and the village, took their name from Mayn Myannos, a Munsee sachem; for generations the river was the main route in and out of eastern Greenwich. Then in 1869 two developers, the New York real-estate broker Jeremiah Atwater and the attorney Luke Vincent Lockwood, bought up the Neck, built a railroad station, and renamed the place “Riverside” — a prettier, sellable name to lure summer New Yorkers up the new line. The bet paid off. The oystermen’s neck became one of Fairfield County’s most refined railroad suburbs, and the old name survives mostly in the river that still borders it.
Why People Visit Riverside
Riverside rewards visitors who like the quiet, watery side of the Gold Coast: sailboats on the Mianus, shaded streets, and a handful of real landmarks close together. Add the Sound-side parks and the easy ride to the city, and the genteel calm makes its own case.
