Built in 1914 by Kansas City millionaire lumberman Robert A. Long, the farm was the largest construction project of its kind in the United States. Long and his famed daughter and horsewoman, Loula Long Combs, once greeted royalty, movie stars, and business magnates at the mansion. Today, Longview Mansion is a premier estate for weddings and special events. Groups of 10 or more visiting Lee’s Summit are invited to arrange a unique luncheon or dinner, including a guided tour of the historic mansion.
