Benjamin Franklin Allen, Iowa's first millionaire, built Terrace Hill as his family home in 1869 with the help of Fred Hubbel. Ultimately, Frank Allen built Terrace Hill as a monument to his wealth, and Fred Hubbell saved Terrace Hill from the fallout of Allen's bankruptcy. Today, Terrace Hill is the home of Iowa Governor Chet Culver, First Lady Mari Culver and the First Family. This beautiful mansion is filled with art, antiques and architecture that remind visitors of Iowa’s rich history and heritage.
