Heritage Partnership: Exploring the Unknown
An 1858 photograph of Mount Vernon, the home of George Washington, showing its dilapidated condition, and the addition of a side porch and balustrade after Washington's death. In 1860 the Mount Vernon Ladies' Association took possession of the estate to preserve and restore its historic structures and landscape to their 18th-century appearance. The association is the oldest national historic preservation organization in the United States. Photo: Courtesy Mount Vernon Ladies' Association.
