Over a million people watched The Diamond Jubilee Pageant on the River Thames on Sunday.
The once-in-a-lifetime, record-breaking event took place on Sunday afternoon.
A thousand boats sailed, rowed, or motored down the river, breaking the record for the largest parade of boats.
Nothing like this has happened for around 300 years, and not even the British weather could dampen anyone's spirits!
Ore tells the story of the amazing day.
