The tell-tales that show how much Nottingham castle has moved

There's plenty to read about Nottingham castle and if you want you can take a look around, but how about getting up close and personal and looking at the less obvious.

You can see some bricks that look out of place. They are tell-tales, put in to check the movement of the castle back in 1939. Thankfully they haven't moved very much which shows the building has solid foundations.

Until the 1970's a plant called Nottingham Catch Fly used to grow here.

Vegetation that has established itself in the rock around the castle

When the castle burnt down during the Civil War (17th century) limestone was released creating the ideal conditions for the plant to thrive.

It was a while flower like a campion. It grew profusely until the gardeners go so fed up they pulled it all out.

But you can still see other vegetation like wild wallflowers, typical of old buildings. They thrive because of the mineral content released by the breakdown of rocks.
