From beneath the 90-foot (30-meter) portico, lies an expanse of sloping lawn along the Potomac River as it flows past Mount Vernon. This 17th-century plantation house was once home to the first President of the United States, George Washington. The property was originally owned by Washington's father, Augustine, and George replaced a smaller, more modest home with Mount Vernon when he came into the property, beginning in 1758. Today, costumed guides narrate the history of the elegant mansion and of the surrounding buildings, which have been preserved to reflect the days when the first president resided here. The state also features tours around the 500-acre (200-hectare) estate, including its surrounding buildings, and historic exhibits that recreate farming techniques and colonial games. Awash in elegant semblances of Palladian architecture, Mount Vernon is a treasured centerpiece of history and culture.
