The coronation of King Charles III is going to be the biggest royal event of the year.

From carriages to crowns, and processions to parties there's going to be a lot to see and take in.

So let Newsround give you some pointers on five things to watch out for during the day.

Let's start with the crown itself. It's the centrepiece of the Coronation and there's even an emoji of it!

The St Edward's crown was made in 1661 for another Charles - King Charles II.

But FYI - it's a copy of an older crown thought to have been used since the 11th Century.

What happened to that one, you ask? Well, it is said to have been melted down when the monarchy was abolished and Oliver Cromwell was in charge from 1653-1658.

Westminster Abbey is one of the most historically important buildings in the UK.

It saw William the Conqueror crowned in 1066 and has been used to crown kings and queens ever since.

It's also been the place of funerals - the Queen's took place here - and weddings too - Prince William and Catherine got married here.

It's also the final resting place of kings, queens and famous people - including writer Charles Dickens.

About two thousand people are expected to attend the coronation - sorry, it's invite only.

Among them will be the Royal Family, kings, queens and presidents from around the world.

But there will be some people missing however: US President Biden won't be there although, his wife will.

And while Prince Harry is coming, Meghan and their kids Lilibet and Archie aren't.

One of the big moments in the day will be the processions.

For the journey to the Coronation, King Charles will be in this very fancy carriage - the Diamond Jubilee State Coach. It comes with heaters, air con and electric windows.

But the journey home will be in the still fancy but less luxury Gold State Coach - Queen Elizabeth called it 'horrible' - Oh dear!

You may have seen the Crown Jewels in the Tower of London, but they'll be in use at the Coronation.

The orb is a golden, jewelled ball, with jewel cross on it. It's designed to say that the new monarch's power comes from God.

The sceptres look like big golden sticks covered in jewels.

They are meant to represent the monarch's power and rule - and have been used at every coronation since 1661.

The orb and sceptres are part of the crown jewels, kept guarded in the Tower of London, so if you were thinking of borrowing them you can forget it!
