Rock Ledge
Why it's listed
Rock Ledge is a country estate in southwest Rhinebeck, built around 1904 to 1906 for Mr. and Mrs. William Starr Miller. New York City architects Frank Hoppin and Whitney Warren designed it. The centerpiece is a three-story rusticated stone manor house in the Italian Renaissance manner, with a ceramic tile hipped roof, quoins, arched openings and iron-railed balconies. Around it stand a stone carriage house, a stone barn, a guest cottage, two round pump houses, and, about half a mile away, a stone stable with its own pump house, cistern and slab bridge. Together, nine dependencies and support structures contribute to the estate, which now covers about 401 acres of a once larger 500-acre tract. The estate was listed for its architecture. Its formal, classical design is unusual in a rural setting and sets it apart from other early twentieth-century Rhinebeck estates. Its finely crafted stone outbuildings also continue the local masonry tradition. Later uses included a novitiate, a school and a treatment center, which altered the interiors.
Significance in brief: The nomination argues the estate is architecturally significant as a distinctive example of early twentieth-century country estate architecture in Rhinebeck. Its formal, classical manor house contrasts with the more picturesque estates of the period. The surviving stone dependencies and much of the original acreage show how Hudson Valley country seats were developed. The stonework continues Rhinebeck's tradition of masonry construction.

What listing means for this property
This is a historic district. Buildings within its boundary are either contributing (they add to the district's significance) or non-contributing. Owners of contributing income-producing buildings can claim the 20% federal rehabilitation tax credit; homeowners should look at state credits. National Register districts impose no design review by themselves; a local historic district ordinance, if one exists, does (the difference explained).
