You may know it was the home of the father of our country, but what else do you know about Mount Vernon, George and Martha Washington's mansion in Virginia? Take our quiz to find out.
The home is literally on a small mountain — a mount, as it were — along the Potomac River in Virginia.
The mansion began life under George Washington's father Augustine as a farmhouse in 1735. Washington acquired it in 1754 and added on until it reached 21 rooms, 2 1/2 stories and 11,028 square feet (1,025 square meters).
George's father Augustine built the original building in 1735 and named it Little Hunting Creek Plantation.
Lawrence Washington, George's older half brother, named it after his commanding officer Adm. Edward Vernon. Lawrence served under Vernon in the 1740s, during the War of Jenkins' Ear.
George Washington ordered the weather vane in 1787 when he presided over the Constitutional Convention. He asked for "a bird with an olive branch in its mouth."
The yellow pine was rusticated in 1758 to make it appear to be stone. This is done by beveling the edges of the boards to look like blocks of stone and throwing sand onto the wet paint to give it a rough texture.
The two-story porch, or piazza, facing the Potomac River was an unusually grand facade for a private home in the 18th century.
At the time of George's death, more than 300 enslaved people lived and worked at Mount Vernon.
Not only was it the last room added, it was the largest and grandest — the mansion's showpiece. In the New Room, Washington received important guests, displayed art and hosted large (too large for the dining room) dinner parties.
George replaced the stone foundations with brick when he enlarged the home — and still didn't add the man cave.
Nelly, Martha's granddaughter from her first marriage, moved with her brother to Mount Vernon after their father died following the Battle of Yorktown.
He initially refused to be paid as president, but decided that would set a poor precedent and accepted the $25,000 annual salary.
The study contained bookshelves with more than 800 pamphlets, newspapers, books and maps. It also held his "fan chair." Not the chair for his admirers, but a Windsor chair with fans that created a breeze when the sitter pumped simple pedals.
The two had no children together, but they did raise Martha's two children from her previous marriage, then raised two of her grandchildren at the mansion.
All the wealthy women in the New World ordered the trendiest clothes from the old country, England. Invoices show Martha had "satin pumps embroidered with gold." Her wedding shoes, still in the museum collection, were lush purple silk with sterling silver braid.
The 8,000-acre (3,000-hectare) estate already grew rye, so Washington's estate manager, John Anderson from Scotland (of course), suggested distilling whiskey. A still was purchased in 1797.
Despite Washington's misgivings — though not a teetotaler, he wasn't sure whiskey baron was a title fit for a former president — the business was a success. In 1799, the estate produced 11,000 gallons (42,000 liters) for a profit of $7,500 (about $142,000 today).
The rumor of Washington's wooden dentures is apparently just that. The set of dentures at Mount Vernon is made of human and cow teeth and elephant ivory.
It is often reported that Elvis' Graceland in Memphis, Tennessee, is No. 1, but Mount Vernon holds the top spot, with more than 1 million visitors each year.
Martha was in charge of running of the mansion and seeing that the considerable number of visitors were fed, housed and entertained. But her favorite activity was needlework, and she produced beautiful cushions, footstools and bags that can still be seen today.
The large and well-appointed servants' hall wasn't always used for the Washingtons' servants — it was for the use of visitors' servants. And while they had a lot of visitors, who had a lot of servants, it didn't go unremarked that having such a building was evidence of significant wealth.
He died following a virulent throat infection on Dec. 14, 1799, in the second-floor bedroom he and Martha shared for 25 years of their 40 years together. He was 67 years old.
Martha closed up the bedroom where George died and moved to the third floor, taking solace in her Bible and her family as she handled the onslaught of well-wishers, before she passed away on May 22, 1802.
Up-to-the-minute medical care would be appalling to folks these days who are used to reaching for an antibiotic.
Back in the day, it wasn't as easy to tell whether someone was actually dead. George Washington didn't want to go into the ground until they were sure he took his last breath. He lay in his mahogany casket in the New Room at Mount Vernon until his funeral.
It says "I am the resurrection and the life." The other quotes are from Alexander Hamilton's tomb at Trinity Church in New York and from Maj. Gen. Henry Lee's eulogy to Washington.
His will expressed his opposition to slavery and his wish that his slaves be emancipated following Martha's death.
Martha freed George's slaves (she owned many that weren't legally hers to free — long story) a year after he died, when it was feared the slaves, ready for freedom, might hasten Martha's death to achieve it.
Martha had a life interest in the estate, but it wasn't hers to pass on. George's nephew, a U.S. Supreme Court justice, inherited it.
In 1858 the organization bought the house and 200 acres (81 hectares) for $200,000 to restore and maintain it. The property became the first national historical tourist attraction.
