This stately Georgian mansion was built in the 1770s for George Washington's only sister, Betty Washington, and her husband, Fielding Lewis, one of Fredericksburg's wealthiest men and a financier of the American Revolution -- so much so that he had to sell Kenmore to liquidate his debts. He died a few weeks after the victory at Yorktown. Today, the house sits on three of the original plantation's 1,300 acres and has been architecturally restored to its Colonial elegance. The 40-minute tours explain the lives of the inhabitants and their servants. In addition to the elaborate molded plaster ceilings and cornices, much of the woodwork and paneling are original. Be sure to explore the famous gardens, restored and maintained according to the original plans by the Garden Club of Virginia. The George Washington Foundation owns the home and sponsors many special programs.
