Joseph Sinnott Mansion, Renaissance Revival mansion in Rosemont, Pennsylvania, United States
The Joseph Sinnott Mansion is a Renaissance Revival residence containing thirty-two rooms, six decorated chimneys, numerous dormer windows, and turrets. Its exterior walls feature fifty-two carved limestone figures that provide ornamental detail across the facade.
The mansion was constructed between 1889 and 1891 as a private residence for whisky distiller Joseph Sinnott. In 1927 it became the principal building of Rosemont College and transitioned to serve the institution.
The stained glass window displays the Sinnott family coat of arms with their Latin motto above the main staircase. Irish heritage influences the decorative choices throughout the residence.
The building underwent complete system renovations in 1999 that updated electrical, heating, and plumbing systems while preserving its historical character. As part of a college campus, the exterior is typically accessible during daylight hours, though visiting the interior may require prior arrangement.
The Gaelic name Rathalla translates to 'home of the chieftain on the highest hill' and reflects the Irish heritage of its original owner. This name remains attached to the residence and shapes its identity today.
