After the ceremony, the President and other dignitaries headed inside the U.S. Capitol for a luncheon. Hanging on a wall directly behind the head table was a view of Niagara Falls.
The painting was done by Dutch artist Ferdinand Richardt in 1856.
The placement is thanks to Senator Chuck Schumer, who is the chairman of the Inaugural Ceremonies.
Schumer says the view of the falls goes along with the theme of the day "Faith in America's Future."
"For me as a New Yorker, Niagara Falls never fails to inspire a tremendous awe of the beauty of our great country," Schumer said.
Schumer says the falls represent the power of America's natural resources.
