Hasbrouck Park, Kingston's first official downtown park, opened in 1920 and covers 45 acres. Much of the park was mined by the Newark Lime and Cement Company in the late 1800's and early 1900's, helping spur the growth of Kingston's Rondout section. Limestone from the park was used in the construction of famous monuments, including the Brooklyn Bridge. During the Great Depression, the Works Progress Administration added a picnic pavilion, tennis courts, a handball court, and a wading pool in the 1930's. In the 1960's, the John F. Kennedy Elementary School was built on the park's northern part. The park now includes a modern playground, a softball field, hiking trails, a basketball court, a remodeled cobblestone building for workshops, meetings, and summer recreation programs, and a pavilion overlooking the Hudson River.
