Donald Trump will return to the White House after being sworn in as the 47th US president in an inauguration ceremony that combines grand tradition and moments of intimacy.
Here are some of the most striking images from the day so far.
Last minute change of plan
The ceremony usually takes place on a specially built stage in front of the US Capitol building, with VIP guests on the platform and thousands watching from the Mall.
But a forecast of freezing temperatures with a wind chill of -13C (9F) prompted a decision to move the ceremony inside the Capitol building’s Rotunda.
Trump supporters who had travelled to the capital to see the ceremony have flocked to the Capital One arena to watch it streamed live on big screens.
Church service
Trump spent the night before the inauguration at Blair House, just across Pennsylvania Avenue from the White House, as is traditional for incoming presidents and as he himself did before his 2017 inauguration.
Trump, his wife Melania, and incoming Vice-President JD Vance and his wife Usha attended a church service at St John’s Episcopal Church.
Rotunda ceremony
Guests at the inauguration ceremony in the Rotunda of the Capitol building included former presidents, foreign dignitaries, Trump’s family and his picks for his new administration.
