This week in 1666 a serious fire damaged the City of London - now known as the Great Fire of London.
The fire burned for five days and destroyed 80% of the City.
To mark the anniversary of this historical event, we're looking for some very special Press Pack reports.
Imagine it's 1666 and you're a journalist live on the scene, reporting on what's happening around you as the blaze is taking hold.
- What did you see?
- What did it feel like?
- Maybe you spoke to some of the residents fleeing their homes?
You can use the links on the right hand side to help you with the factual elements in your report - which should be no longer than 400 words.
We'll publish the best five on the site.
These Press Packers will also receive a family ticket to visit the London Dungeon - which has its very own Fire of London experience!
But get creative quick as this Press Pack competition closes on Monday 15 September.
