The US capital has been preparing for public events to commemorate the inauguration of President Barack Obama for a second term.
Hundreds of thousands of visitors are expected in the capital.
Ahead of the public oath the President makes on Monday, he was officially sworn in on Sunday in a small ceremony at the White House.
During his inauguration speech, Obama will lay out his plans for the next four years.
But for the moment, many Americans are focused on celebrating the historic day itself.
Business has been booming in DC shops and stalls, packed with Obama memorabilia.
