The park is frequently used for equestrian events, including on the prairie on the north and west sides.

In 1854, Hyacinth Renard built Jarville, a Greek Revival-style home on the land that would later become Queeny Park.

[2] The land around Jarville was eventually purchased by Monsanto chairman Edgar M. Queeny.

In 1964, he sold the land to a realty investment company and donated the proceeds to Barnes-Jewish Hospital in St. Louis.

In 1970, the County bought the estate from the investment company and began to convert it into a park.
