Charles Krug House

The Charles Krug House, also known as the Krug House or the "Krug Mansion" is a former residence at 103 N. Douglas Street, Glendive, Montana, US, designed by St. Louis, Missouri-based architect Herbert C. Chivers (1869-1946). It was listed on the National Register of Historic Places in 1976. The Krug Mansion now houses Sugar Plum Fine Jewelry and is no longer a private residence.

Charles Krug (1846–1929) was a successful rancher and president of the Merchants National Bank. In 1900 at age 54, Krug married Annie A Hackney (1868-1950), the mother of two daughters. They had five more children together. The house was built in 1906 to accommodate the large family.

The NRHP nomination states: "The Krug House is a grand expression of a by-gone age, reminding our current generation of the integrity and perseverance of Charles Krug, and of the timeless values of fine construction that are represented in this eastern Montana home."
