The newly-renovated Jimmy Carter Library and Museum opened Thursday, on the former U.S. president's 85th birthday.
Former President Carter and his wife Rosalynn attended the ceremony for the museum in Atlanta, in the southern state of Georgia.
The renovations took about five months to complete and cost about $10 million.
New museum features include an interactive exhibit to give visitors a behind-the-scenes look at a day in the life of a president.
The exhibits also focus on Mr. Carter's work after he lost his bid for re-election in 1980. Since leaving office, the Nobel Peace Prize laureate has worked to mediate conflicts, monitor elections around the world, and eradicate poverty and diseases such as Guinea worm disease and river blindness.
The museum still has some of its original displays, including a full-scale replica of the White House Oval Office.
