Children from across Huntingdonshire showcased their love for books by dressing up as their favourite book characters.
From Batman to Superman, youngsters swapped their uniforms for superhero costumes to celebrate the annual event.
World Book Day was first held in the UK in 1995, and since then schools from across the country have held yearly events to celebrate novels.
St Peter’s School, in Huntingdon, marked the day by welcoming author Penny Joelson to talk about her book ‘I Have No Secrets’.
Meanwhile, children from Ramsey Community Junior School were asked to dress up as a ‘goodie and baddie’ from any book. Pupils at Holywell Primary School, Middlefield Academy, Cromwell Academy, and Winhills School were all also taking part in the festivities.
The day, which is usually held in April, but is sometimes moved depending on the Easter holidays, tries to promote reading by giving every child a book voucher.
