London is built on an assembly of interlocking cogs - business, sociality, history, culture and modernity - but what keeps the clock ticking? These guided walking tours will help explain how science has contributed to the city you see today.
The walk is approximately 4km/2.5 miles long (about 2 hours) and it starts at the historic Tower of London. Anyone can join in and the walks take place every day from Wednesday 30 June to Sunday 4 July - book tickets here.
The tour finishes at Southbank Centre, where everyone is welcome to visit the Royal Society Summer Science Exhibition.
