On a beautiful 126-acre estate of rolling hills overlooking the Potomac River, visitors can explore and contrast the architectural and historical backgrounds of two unique homes and enjoy a natural retreat in the midst of the busy Route 1 corridor. Resource <a href="http://www.woodlawnpopeleighey.org/pope-leighey-house">Pope-Leighey House:</a> During the 1930s, Frank Lloyd Wright set his formidable attention towards designing affordable middle-class residences. More than 100 of these modest homes, referred to as Usonian, thought to mean “the United States of North America,” were constructed between 1936 and Wright’s death in 1959, including the Pope-Leighey house (1940). Commissioned in 1939 by Loren Pope, a journalist in Falls Church, the residence was sold to Robert and Marjorie Leighey in 1946. <a href="http://www.woodlawnpopeleighey.org/woodlawn">Woodlawn Plantation:</a> Woodlawn, the first site operated by the National Trust, was part of George Washington’s Mount Vernon. In 1799, he gave the site to his nephew, Lawrence Lewis, and Lewis’ new bride, Eleanor “Nelly” Parke Custis, Martha’s granddaughter, in hopes of keeping Nelly close to Mount Vernon. The newly-married couple built the Georgian/Federal house designed by William Thornton, architect of the U.S. Capitol. In 1846, the entire plantation was sold to Quaker timber merchants, who purposefully operated the farm plantation with free labor, making a statement in Virginia on the eve of the Civil War. At the turn of the twentieth century, two separate owners, Paul Kester and Elizabeth Sharpe, lovingly restored the property using the best Colonial Revival architects and builders. Senator Oscar Underwood from Alabama, an uncompromising advocate for civil rights, lived at the mansion from 1925 until his death in 1929. Operated as a historic house museum since 1949, Woodlawn is an interesting case-study of the cultural relevance of the house museum. Woodlawn relies on local support and engagement to succeed.

Sandy Spring is the center of a unique Maryland community, a network of rural villages settled in the 1720s by members of the Religious Society of Friends, known as Quakers. The Sandy Spring Museum's extensive artifact and document collection illuminates the rich 18th, 19th, and 20th century history that took place in this small Maryland town. From the hand-made doll of a child to the tools of a farmer, the museum’s artifact collection represents the daily lives of generations of local residents. We collect records of individual, families, corporations, and groups, documenting the life of the community – its politics, economies, work, play, and family life. The collection features a number of items relating to the War of 1812, such as objects and documents from James Madison's 1814 flight from the advancing British army, during which he spent a night in Sandy Spring. The museum's collection also includes a letter from Dolley Madison to the mother of the prominent local Quaker Edward Stabler, who would later design the seal for the U.S. Senate and Supreme Court. Stabler had been jailed during the War of 1812 as a result of his pacifism. In the letter, Dolley Madison promises Stabler's mother that she will intercede for his release. Additionally, the many collection items relating to manumission in Sandy Spring offer visitors a look into antebellum Maryland's uniquely hybrid border-state society, which consisted of slaves, free blacks, and whites working side-by-side. The extensive manumission records from 1780-1820 document the local Quaker-led effort to end slavery, while the numerous genealogical, property, commercial, and religious records of the free black families in the community from emancipation through the 20th century offer visitors a vivid picture of the everyday life of African Americans after the Civil War. The records from Cloverly, a facility next door to the museum where exhausted Union Army nurses were treated, today reside in the permanent collection. The museum also has records of the constant strain on agriculture from both the Union and the Confederate armies passing through the area repeatedly in search of food, horses, and cloth during the Civil War.

The site that is now the National Park Seminary Historic District was originally a wooded glen and tobacco plantation. It was developed in 1887 as a resort hotel designed by the noted Washington architect T. F. Schneider and known as Ye Forest Inne. When the hotel proved to be unsuccessful, John and Vesta Cassedy rented and later purchased the property to create, in 1894, National Park Seminary, a finishing school for young women. Most recently, in October 2004, The Alexander Company and EYA's plan to save all of the historic buildings, to add new townhouses in compatible styles, and to transform the Seminary into a unique residential community of apartments, condominiums, and single-family homes has been approved by local planning and historic preservation agencies.
