The Paradise Furnace, also known as the Mary Anne Furnace, is a national historic district that is located in Trough Creek State Park in Todd Township in Huntingdon County, Pennsylvania. It was listed on the National Register of Historic Places in 1990. History and architectural features
This consists of two contributing buildings and one contributing structure that are associated with a former iron furnace. They are the ironmaster's mansion, furnace stack, and a log workers' house. The ironmaster's mansion, which was built during the 1830s, is a two-and-one-half-story stone house that was designed in the Georgian style. The furnace stack dates to the 1830s, and is a twenty-eight-foot, square, coursed rubble stone structure, which measures between fifteen and twenty feet tall. The ironworks operated from the late-eighteenth century into the mid-nineteenth century, when economic conditions caused it to be fired. The two-story log house dates to the late-eighteenth century. It was converted for use as the park visitor's center/museum in 1982. It was listed on the National Register of Historic Places in 1990. References
