Head to the City on 23 and 24 July for the return of the amazing Archikids Festival, celebrating our city's brilliant buildings.
This is the fourth outing for the annual festival, aimed at five to 11 year olds, which takes place at venues across the city, including The Gherkin, Beavis Marks, Whitechapel Gallery, Broadgate Circus and St Botolph without Aldgate.
This year's festival programme includes more than 25 different activities for kids and their families to take part in, with the aim of opening up London buildings that aren't usually accessible to children.
Budding engineers can redesign the city's skyline, build a shoebox house, create a stop-motion animation, and design and fly their own kites.
Lego lovers can spend the day tackling a fast-paced building challenge to see who can create the biggest and best Lego structure.
In addition, there's the chance to create catapults, balloon-powered cars and paddling boats to carry ping pong balls safely across engineering-obstacle courses.
Here's a video of last year's festival to get you even more inspired.
