WHAT WE DO: Preservation

In addition to restoring, maintaining and operating the Neill-Cochran House Museum in Austin, Texas Dames join the other State Corporate Societies in supporting three important historical properties:

dumbarton2Dumbarton House, the national headquarters in Washington D.C., was purchased by the NSCDA in 1928.  It is one of America’s outstanding museum houses of the Federal Period and is listed in the National Register of Historic Places.

Gunston Hall

Gunston Hall,
a 550 acre plantation at Mason Neck, Virginia, is a National Historic Landmark.  It was built in the mid 1700’s by George Mason, the author of the Virginia Declaration of Rights, upon which the National Bill of Rights was modeled.  The NSCDA administers Gunston Hall.

Sulgrave Manor
is the English ancestral home of George Washington.  Located 70 miles from London, the Manor was built in 1539.  The NSCDA established an endowment for Sulgrave in the early nineteen hundreds and today, the NSCDA is involved in overseeing the endowment and other fund raising activities in the United States to benefit the Manor.


The NSCDA actively participates in preserving and operating more than 90 historical sites in the United States.
Forty-one of those properties are owned outright by the State Societies of the NSCDA and thirteen more include museum collections owned by the Dames. NSCDA members provide substantial volunteer and financial support to thirty more properties. These diverse historic houses/museums/collections encompass America’s history from the 17th century until the early 20th century.  In November 2000, the NSCDA received the prestigious Trustee Emeritus Award for Excellence in the Stewardship of historic sites from the National Trust for Historic Preservation.  The NSCDA historic properties are now known collectively as
Great American Treasures:  The NSCDA Museum Alliance.
