History: Travelers heading west from 1812 to 1857 used this park as a campsite long before the founding of Olathe. During the Civil War, this location was a popular campground for Union soldiers. It has also been the site of a grist mill, general store, creamery and ice house, and also a privately owned pond where the citizens could fish, swim and ice-skate. The swimming pool was built under the Works Progress Administration (WPA) project. A parking lot and tennis courts were added north of the pool. The name was changed from City Park to Mill Creek Park in a city contest for renaming the park. The 4 acre park is the City's oldest neighborhood park. Dedicated in 1935, Mill Creek Park serves the downtown area.
