What began in 1904 as hunting lodge for James Clise, a Seattle banker, gradually expanded into the 28-room country great house that is now known as Clise Mansion.  Clise named his estate Willowmoor, and it became a working showplace farm known for breeding Morgan horses and Scottish Ayrshire cattle. Clise sold the farm in the 1920s, and it changed hands several times before being purchased by Everett lumberman U.M. Dickey in 1941.  Dickey leased the farm to three men who continued the dairy operation, renaming it "Marymoor" after a daughter. In 1959 an investment firm bought the farm with the intent to develop it, but King County saved the land for a public park. Willowmoor Farm, which includes the Mansion and the adjacent Windmill, is listed in the National Register of Historic Places.
