About Oak Knoll Park

Clayton Early Childhood Center is located at 1 Oak Knoll Park, in one of two stone mansions on 14.5 acres of rolling terrain. 

Oak Knoll is the second largest park in the city of Clayton, MO, with a variety of botanical life, a quarter mile walking path, picnic areas, a public playground, and a pond decorated with a fountain and inhabited by turtles and ducks.

In the early 1800s, the park was part of the 300-acre Kennedy Farm. Charles Rice, a local lawyer, bought the property in 1905 and built 1 Oak Knoll for his family. 

In 1958, the grounds became a municipal park, named for a stand of 150-year-old Post Oak trees that still remain.
