Oak Hill Cottage
Also known as: Shane's Castle
Why it's listed
Built in 1847 on a small hill overlooking central Mansfield, Oak Hill Cottage, also known as Shane's Castle, is a Gothic revival house that the nomination describes as the oldest building of substance in the city. Architectural authority Ralph Adams Cram is quoted as calling it the one perfect Gothic house in the United States. Because it was designed and built before 1850, when the style became popular in modified form, it kept a pure Gothic character. After Dr. Johannes A. Jones bought it in 1864, the house became a show place and a center of Mansfield social life, hosting politicians and educators, including a recital by Margaret Wilson during a World War I Liberty Loan drive. It is also believed to be the setting for Louis Bromfield's novel The Green Bay Tree. Only minor alterations are recorded, and the local historical society has preserved the house and many Victorian furnishings, though the grounds, gardens and orchards have been reduced.
Significance in brief: The nomination calls it the oldest building of substance in Mansfield and a pure example of Gothic revival, built before the style was modified after 1850. It was also a social center after Dr. Johannes A. Jones bought it in 1864, hosting politicians and educators. It is believed to be the setting of Louis Bromfield's novel The Green Bay Tree.

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.
