The Dairy in Prospect Park, unknown date. Designed in 1869 by Calvert Vaux and completed by 1870, this stone cottage, known as the Dairy, once stood just north of Boulder Bridge in Prospect Park’s Midwood. It became a main attraction to 19th century picnickers as it offered park-goers a reliable alternative to the vile milk that was then being produced by Brooklyn’s diseased cows. In the summer of 1871, over 11,000 quarts of milk were produced at the Dairy alone. Cold beef, ham and tongue sandwiches and pickled oysters were also sold inside the cottage. The Dairy's interior included "retiring rooms" for people to relax and recharge next to a fireplace. The Dairy was razed in 1935 to make way for the zoo. Since then, picnickers in the park have shifted across the lawn to Long Meadow.
