Outdoor Lighting in Brookville, NY.

The geographic Village of Brookville was formed in two stages. When the village was incorporated in 1931, it consisted of a long, narrow tract of land that was centered along Cedar Swamp Road (Route 107). In the 1950s, the northern portion of the unincorporated area then known as Wheatley Hills was annexed and incorporated into the village, approximately doubling the village’s area to its present 2,650 acres (1,070 ha).

When the town of Oyster Bay purchased what is now Brookville from the Matinecocks in the mid-17th century, the area was known as Suco’s Wigwam. Most pioneers were English, many of them Quakers. They were soon joined by Dutch settlers from western Long Island, who called the surrounding area Wolver Hollow, apparently because wolves gathered at spring-fed Shoo Brook to drink. For most of the 19th century, the village was called Tappentown after a prominent family. Brookville became the preferred name after the Civil War and was used on 1873 maps.

Brookville’s two centuries as a farm and woodland backwater changed quickly in the early 20th century as wealthy New Yorkers built lavish mansions. By the mid-1920s, there were 22 estates, part of the emergence of Nassau’s North Shore Gold Coast. One was Broadhollow, the 108-acre (0.44 km²) spread of attorney-banker-diplomat Winthrop W. Aldrich, which had a 40-room manor house. The second owner of Broadhollow was Alfred Gwynne Vanderbilt Jr., who was owner of the Belmont and Pimlico racetracks. Marjorie Merriweather Post, daughter of cereal creator Charles William Post, and her husband Edward Francis Hutton, the famous financier, built a lavish 70-room mansion on 178 acres (0.72 km²) called Hillwood.
