Ryerss Mansion
Also known as: Burholme Park
Why it's listed
Built in 1859 for merchant and railroad president Joseph Waln Ryerss, this three-story roughcast stone Italianate house crowns a hill in the Foxcroft section of Philadelphia. Its tin hipped roof carries a central tower topped by an egg-shaped dome, and a one-story porch runs along three sides. Joseph Ryerss named the estate Burholme after the Waln family seat in England. His son Robert Waln Ryerss, an attorney and collector, left the property to the City of Philadelphia for use as a park, library and museum, and it was opened to the public in 1910. Much of the original interior survives, including marble and slate mantels, molded plaster ceilings and a continuous rail staircase. The house holds family art objects, particularly Oriental artifacts, and the family library. The nomination regards it as a well-preserved example of the lifestyle of the nineteenth-century business aristocracy. The Ryerss also founded the Ryerss Infirmary for Dumb Animals, and family pets and horses are buried on the grounds.
Significance in brief: The nomination argues the house reflects the cultural, philanthropic and economic achievements of American businessmen in the late nineteenth and early twentieth centuries. It is significant for its opulent Italianate architecture and for preserving original family collections and interiors that document the tastes and interests of a business family of the era. The Ryerss family's commitment to animal welfare, including the Ryerss Infirmary for Dumb Animals, is also cited.

What listing means for this property
National Register listing is honorary for a privately owned home: it does not by itself restrict what an owner may do with their own money, and it does not require public access. Restrictions come from local landmark or historic-district ordinances, which are separate (how they differ).
Owner-occupied houses are not eligible for the 20% federal rehabilitation tax credit, which applies to income-producing buildings, but many states offer credits for homeowners. Listing also opens the door to preservation easements and to buying a plaque. Start with what listing means for homeowners, renovating a listed house and selling one.
General information, not legal or tax advice. Rules change; confirm with your State Historic Preservation Office or a qualified adviser.
