The private residence at Number One Observatory Circle was built in 1893. It's just 2.5 miles from the White House, but feels worlds away.
It is located on the grounds of the US Naval Observatory, where scientists study the sun, moon, and stars for navigational purposes.
For 30 years, it served as the home of the superintendent of the US Naval Observatory. Then in 1923, it became the official residence for the head of the Navy.
In 1974, Congress designated the house as the home of the vice president.
But the first vice president didn't move in until three years later, when Walter Mondale was elected second-in-command under President Jimmy Carter.
The ground floor has a reception hall, living room, sitting room, dining room, garden room, lounges, pantry kitchen, and veranda.
On the second floor is the master suite, another bedroom, a study, and a den. The attic used to be servants' quarters, but now has four bedrooms for children. The main kitchen is in the basement.
Every vice president has lived there since Mondale, bringing their own unique touch to the home's 9,150 square feet.
"It really changed from one administration to another," Charles Denyer, an historian and author of a new book about the residence, told USA Today in November.
George H.W. Bush installed a horseshoe pit on the grounds when he was vice president.
When Dick Cheney and his family moved in, they decorated the home using a neutral color scheme of of creams and greens.
People can donate to the Vice President's Residence Foundation, a non-profit organization created in 1991, to help pay for decorating expenses.
When Al Gore's family lived there, lacrosse sticks and drumsticks were reportedly always lying around.
The house features Queen Anne-style architecture, and a gorgeous porch that wraps around the front corner.
Dan Quayle added a swimming pool and exercise room during his tenure. In 2010, Joe Biden told reporters that Quayle was his "favorite vice president" because he helped build the pool.
Jill Biden, Joe's wife, was also grateful. "Each person has added something to make the home better for the next family," she told The Washington Post.
She was also especially fond of the "serenity" of the place. "When times get tough, and there were some pretty tough times for the Bidens, you could sit outside and reflect. It was very healing," she said.
Numerous leaders and dignitaries have been to the residence over the years. In 2015, Biden hosted Ireland's Prime Minister Enda Kenny.
When the Pences moved in, Jill Biden told them that the Observatory is nothing like Washington, where she said life is truly hectic each and every day.
But the Pences have made the Observatory their home. After moving in, they posed for Inauguration Day photos on the front porch.
They took their most recent official Christmas portrait from what looks like the sitting room. Just like the White House, the Observatory was all decked out for the holidays.
The house can be quite magical during the winter, especially when it snows.
Second Lady Karen Pence, a former art teacher, often paints at the living room table. Two of her paintings are on display at the house.
Since declaring art therapy as her official cause as Second Lady, she has hosted events for US soldiers suffering from PTSD.
Just like their predecessors, the Pences have hosted a broad range of guests, including politicians and world leaders.
In June, US Department of Agriculture Secretary Sonny Perdue joined Karen Pence to unveil the addition of bee hives to the grounds.
Karen also met with Ho Ching, the wife of Singapore's Prime Minister, Lee Hsien Loong, in the garden room in October.
The Pences made use of the spacious patio by the pool in the summer.
But the public rarely gets the chance to see the property for themselves. There are no public tours and the house is hidden from the street. "If you don't know about it, it's not there," historian Denyer said.
