Rosary Hall is as resilient as the Sisters. It has weathered many storms, including fire, hurricanes, and water damage. With an architecture based on the Holy Cross Convent in Regensberg, Germany, the Motherhouse and Novitiate were completed in 1876. In 1920 it grew to include a farm, outbuildings, orchards, a cemetery, and a grotto.
Named a New York State historic landmark, the site was added to the National Register of Historic Places in 2007 which protects and preserves the future of the properties. All renovations accommodating the needs of the retired Sisters, referenced descriptions of the original exterior and interiors. Experts attended every detail with reverence and dedication to the spirit of this great building — not only as a historic site but as the Sisters’ home.
