The Sherrill Mount House, also known as the Fries Hotel, Moundside Apartments, and The Inn at Sherrill, is a historic building located in Sherrill, Iowa, United States. This is one of the few surviving pre-Civil War hotels left in Iowa, and one of the largest early stone structures remaining in rural Dubuque County. The three-story building is composed of native limestone with a cupola on top of the hip roof. It was built along a stagecoach route that traveled along the Mississippi River. At one time it was situated on a 40-acre (16 ha) plot of land on which were several out buildings for an agricultural operation that included an orchard and vineyard. The building also served the community as a post office and meeting hall. Before national prohibition in 1919 the inn included a beer garden, tavern and dance hall. It was at this time that the building was converted into an apartment building. It has subsequently been converted into a bed and breakfast called the Black Horse Inn. The house was listed on the National Register of Historic Places in 2002.
