Joseph Sinnott Mansion, also known in Gaelic as "Rathalla," meaning "home of the chieftain on the highest hill" is the Main Building at Rosemont College. It is a historic home located on the campus of Rosemont College at Rosemont, Montgomery County, Pennsylvania. It was originally a part of the Ashbridge estate and was called 'Rosemont Farm'. However, in 1889, Joseph F. Sinnott, a Whiskey distiller, purchased the 40-acre land. Upon it was built his summer home between the years of 1889-1891 by Hazlehurst & Huckel for $150,000. Edward Hazelhust and Samuel Huckel were both fellows of the American Institute of Architects
