Situated in the Willowmoor farmstead area of Marymoor Park, Clise Mansion offers sweeping views of the surrounding gardens and lawns. On the National Register of Historic Places, "Willowmoor Farm" was owned and developed by Seattle banker James Clise in the early 1900s. The property served as his family's country estate and working showplace farm for his Morgan horses and Scottish Ayrshire cattle. The grounds, which feature a selection of heritage trees, were designed by the Olmsted Brothers landscape architecture firm, the designers of Central Park in New York City. It was Clise who built the park's iconic windmill, which has never been functional!

The Clise Mansion is currently undergoing extensive renovations and is not taking bookings in 2014. Click here to learn about other wonderful King County Parks’ facilities available for your events.
