The Holy Rosary Church Rectory at 220 W. Main in Bozeman, Montana is a brick building that was designed by Fred F. Willson and built in 1912. It was listed on the National Register of Historic Places in 1987. The two-story brick building features Gothic arched windows and a detailed brick design along the roofline, visually linking the rectory to the church. The crenellated (notched) door surround evokes the image of a medieval castle, reinforcing the connection to the Gothic style.
