Mount Vernon was the beloved home of George and Martha Washington from the time of their marriage in 1759 until General Washington's death in 1799. He worked tirelessly to expand his plantation from 2,000 acres to 8,000 and the mansion house from six rooms to 21. Visitors are invited to tour the Mansion house and more than a dozen outbuildings including the slave quarters, kitchen, stables, and greenhouse. They can stroll four different gardens, hike the Forest Trail, and explore the "George Washington: Pioneer Farmer" site, a four-acre working farm that includes a recreation of Washington's 16-sided treading barn. George and Martha Washington rest in peace in the tomb where wreathlaying ceremonies are held daily, and the Slave Memorial and Burial Ground is nearby.

For the child who believes milk comes from the grocery store instead of a cow, for the woman who remembers using a cornsheller on her grandmother's farm, or the family who takes 20th-century technological advances and the farmer for granted, the Delaware Agricultural Museum and Village offers a memorable and educational experience. By preserving the quickly fading agricultural heritage of Delaware and the Delmarva Peninsula, the Museum stands as an important legacy for future generations.
