Originally installed in 1885, in Folkestone, Kent, the Grade II Listed Leas Lift is a funicular railway which carries passengers between the seafront and the promenade. It is one of the oldest water lifts in the UK.
The lift operates using water and gravity and is controlled from a small cabin at the top of the cliff. It has carried more than 50 million people since it opened, in a process that is especially energy efficient. The lift has a very small carbon footprint, as it emits no pollution and recycles all of the water used to drive the cars.
