Langworthy House
Historic house in Iowa, United States
The Langworthy House, also known as the Octagon House, is a historic building located in Dubuque, Iowa, United States. Built in 1856, it was designed by local architect John F. Rague for local politician Edward Langworthy.[2] The two-story brick home features tall windows, a columned entry, and a windowed cupola.[3] Langworthy and three of his brothers were among the first settlers in Dubuque.[4] They were partners in a lead mine, helped to build the territorial road between Dubuque and Iowa City, they farmed, invested in real estate, and they owned a steamboat and a mercantile exchange. The house has been passed down through Langworthy's descendants.[4] It was individually listed on the National Register of Historic Places in 1975,[1] and it was included as a contributing property in the Langworthy Historic District in 2004.[5]
