Riverdale is only about 3 square miles, but boasts top-tier private schools, including Horace Mann, Riverdale Country and Fieldston, as well as two Roman Catholic colleges and a rabbinical school. Bordered by the Hudson River, you’ll have views of New Jersey and the Palisades and Yonkers. Riverdale is steeped in history. In the early 19th century, many wealthy Manhattan residents built country estates in areas such as current-day Fieldston, which was initially developed by the Delafield family. The first house was built in 1911, and Fieldston had become a wealthy gated community by the start of the 21st century. Once an established railroad linked it to New York City, Riverdale became more of a year-round residential community.
Before the wider development of Riverdale, housing consisted of large, architecturally distinguished mansions built in the early 20th century, mostly in Georgian- and Tudor-revival styles. These are mostly concentrated in the Fieldston section of Riverdale, known as the estate area. By the early to mid-1960s, a number of larger brick towers full service building were erected such as Skyview, the Windsors and the Whitehall. Since 2005, central Riverdale has experienced a building boom with the addition of many estate areas that include pre- and postwar buildings. There are condos and co-ops as well as single-family homes in the Fieldston and North Riverdale areas.
