The Main Building, the Joseph Sinnott Mansion — also known as Rathalla ("home of the chieftain on the highest hill" in Gaelic)[citation needed] — served as the first classrooms and student housing for Holy Child College. It was originally built as a summer home for whiskey distiller Joseph F. Sinnott. Completed in 1891, the home was designed by architects Edward P. Hazlehurst and Samuel Huckel.[1] The building was heavily influenced by the Gothic chateaux of the Loire Valley.[2] In 1927, the Sisters of the Holy Child of Jesus acquired Rathalla for $1.00.[3] The building was added to the National Register of Historic Places in 1980.[4]
