Normally state visits see leading figures from national like the prime minister and Commissioner of the Met Police introduced to the visiting foreign leader, but it was just the three senior royals taking part in the ceremonial welcome.
The booming sounds of a double gun salute in nearby Green Park echoed around the palace grounds.
Soldiers from the King's Troop Royal Horse Artillery led 71 horses, pulling six First World War-era 13-pounder field guns, into place, to fire 82 blank artillery rounds at 10-second intervals.
The first 41-gun salute honoured Mr Trump's state visit.
The second round of 41 shots were staged to mark the 66th anniversary of the Queen's coronation on Sunday.
