Saturday marks the 801st Lord Mayor's Show, a procession to celebrate London's new Lord Mayor.
If the Second World War couldn't cancel the Lord Mayor's Show, a bit of miserable weather had no chance of casting a shadow over the festivities.
This year's Lord Mayor of London is Andrew Parmley, who set off in a barge in the morning for the river pageant, and then took part in the elaborate Lord Mayor's procession.
We've got to say, we're pretty partial to his opulent golden carriage - where can we get one for ourselves?
The end of the day will see a spectacular fireworks display between Blackfriars and Waterloo, and what better way to round off the celebrations.
For many, rain is just part of the day. That doesn't mean that it had any effect on the jovial atmosphere.
Luckily, people came well prepared for the wet weather.
Others ditched their rain macs and instead turned up in far more elaborate outfits.
Some people weren't particularly well-acquainted with the parade's long history, and understandably thought it was quite the spectacle.
We mean, it doesn't get better than a giant bottle of wine floating down the street, right?
It's been a bit of a tough week for all of us, so there's nothing like a good old-fashioned parade to really lift the spirits.
It's definitely one of our favourite traditions.
