Heritage Hill State Historical Park, is a 56-acre open-air museum located in Allouez, Wisconsin.

The Heritage Hill Corporation operates, maintains and develops the park under terms of a lease with the DNR.

The Park is divided into four main areas: The Fur Trade, representing the first contact and fur trade industry in Wisconsin; The Growing Community, representing Green Bay's beginnings as a burgeoning metropolis in the late 19th century; The Belgian Farmstead, a representation of immigrant farming communities in the early 20th century; and Fort Howard, a reconstruction of how Fort Howard would have stood on the west side of Green Bay in the mid-19th century.

Construction of highway 172 across the Fox River cut off the farm from the prison and the land fell under the jurisdiction of the Wisconsin Department of Natural Resources.

Preservation of the buildings and its artifacts and the interpretation of the history of Northeastern Wisconsin and its people remains a primary objective.
