KidZania, in Westfield, London, is an educational child-sized indoor city

Forget Peppa Pig World and Legoland, now parents can send their children out to get jobs - as a brand new educational theme park opens in London.

At KidZania, in Westfield, London, children aged between four and fourteen can try out a range of professions - playing a surgeon, firemen or fashion stylist for the day - in an ultra-realistic, indoor replica of a city.

Built over the course of one year the 75,000sq ft. child-sized city, which opened on Thursday, is the equivalent in size to Leicester Square, with the ceiling height of Heathrow Terminal Five.
