Jedward's Big Adventure is a children's television programme airing on CBBC. It is hosted by Irish twins Jedward (John and Edward Grimes) and follows them as they visit various UNESCO historical sites around the United Kingdom. Each teaming up with celebrity guests, the twins are tasked with learning as much about each site as possible, before leading a tour of real tourists and passing on what they've learnt. Two series of five episodes each were produced and broadcast, whilst a third series was extended to 10 episodes, broadcast in January 2014.
