Built in 1910 by famed architect A.J. Gibson, The Daly Mansion is the historic family home of Copper King and founder of Hamilton, Marcus Daly. It is a 24,000 square foot Georgian Revival home sitting on over 40 acres of expansive lawns, gardens, and an arboretum boasting one of the widest and rarest variety of trees in the state of Montana. The home has 24 bedrooms, 15 bathrooms, and 7 fireplaces. Over 2 million dollars in restorations have been completed under the Trust in the Mansion, the grounds, and the outbuildings.
