The Vanderveer Windmill, east of Flatbush Avenue, ca. 1875.

Fittingly, Kings County's foremost windmill was located on the farm of a prominent Dutch family in the Dutch-settled town of Flatbush. Likely built in the first decade of the 19th century (sources vary on the exact yet; some suggest decades earlier), farmer John C. Vanderveer's windmill was originally equipped with 26-foot "sails." Around the early 1830s, the sails were removed and the mill was converted for simple grain storage.

Vanderveer's windmill played an unlikely role in the Draft Riots of 1863. Concerned that violence directed at African-Americans would spread from riots in Manhattan to Brooklyn and beyond, black residents of Flatbush took shelter in the windmill as a precautionary measure.

Sixteen years later, on March 4, 1879, the windmill caught fire in the early morning hours in a blaze visible from Brooklyn City Hall (now known as Borough Hall).
