The Olsen House is a historic house in Helena, Montana. It has been listed on the National Register of Historic Places since March 22, 1991.^[2] It stands opposite St. Peter's Cathedral.

History[]

The plot of land was purchased in 1874 by Amelia Dissa, and her husband Louis Derrick built a one and a half-story cottage facing Park Avenue.^[3] It was built with wood and designed in the Gothic Revival architectural style.^[3]

After he died in the late 1870s, she married Ingethen Olsen, an American pioneer who owned a ranch in Fergus County, Montana, but the house remained in her name.^[3] By 1884–1885, they built a two-story rectangular addition and a gable.^[3] After Olsen died in 1904, his wife replaced the wooden cottage frame with a two-story front built with bluestone; it was completed in 1908–1909.^[3] When she died in 1918, the house was inherited by her daughter Amelia M. Olsen, who lived there until 1946.^[3]

Four years later, in 1950, the house was purchased by John Conway Harrison, who was elected as a justice of the Montana Supreme Court in 1961.^[3] He lived in the house until 1988, and he sold it to Robert Haseman in 1989.^[3] The house was later used as offices.^[3]
