Nine brand new gargoyles have been added to the world famous Bodleian Library in Oxford. Each one has been designed by children who won a competition.
There used to be gargoyles on the building but they've crumbled away over the years. Traditionally they tend to be unusual creatures.
Author Philip Pullman unveiled the sculptures. He thinks that the mystical creatures jump down from the building's walls and fight each other at night!
The winning designs feature characters from books written by authors who have lived in Oxford. Just like Tweedledee and Tweedledum from Lewis Carroll's Through the Looking Glass.
As well as fictional characters one of the new gargoyles is of Sir Thomas Bodley who founded the library. They're all on the north-west side of the library which was first built in 1602.
