If you've been wondering who has been putting up homemade blue plaques all over Norwich and why... then we can reveal all! It's a protest at the lack of official ones in the city honouring women. A Twitter account called Rosie's Plaques has claimed responsibility. Natalie Gray has been meeting some of the rebels behind the pop up protest .
Norwich has over 300 plaques celebrating the places, the events and the people - but only 25 of them honour women.
So a group of women set out to do something about that. They've put up their own plaques around the city. One, at the Guildhall, honours Mabel Clarkson, who became a Lord Mayor of Norwich and a city councillor before women achieved the vote.
The twitter group Rosiesplaques is behind the protest ... they want to remain anonymous but they explained why they'd put the plaques up.
A spokeswoman for Norwich City said they were enjoying the temporary art installation and they would consider any application from anyone wanting something more permanent.
