Residents are outraged after the walls of a castle were sprayed with graffiti.

The painting was first spotted on the side of Rochester Castle yesterday afternoon.

One woman who lives in the area said: “It’s just appalling that our castle has been treated like this.

“Kids have no morals anymore, they should be made to clean it up themselves if they get caught.

“They wouldn’t do it in their own homes.”

She said the vandals would have had to climb over some bricks to get to the back of the castle and gain access to the site that was graffitied.

A flower, a warning sign and a drawing of a duck accompanied by the word QUACK are among some of the things that can be seen on the wall.

A mum who takes her children on walks around the castle grounds regularly described the graffiti as “despicable”, while one man said CCTV needs to be installed in the area to stop a similar thing from happening again.

Medway Council has confirmed it is making arrangements to get the graffiti removed, under Historic England’s guidelines and advice for removing graffiti from historic sites.
