1. South Foreland Lighthouse, Dover
One of the most famous and iconic of its kind, South Foreland sits atop the White Cliffs and has long been at the forefront of lighthouse innovation.
The first structure in the world to use an electric beam, it was also instrumental in the development of radio wave technology, receiving the first international transmission from France in 1899.
Opened to the public in 1988, the tower is now owned by the National Trust – and, on a clear day, you can even make out the French coast. Ooh la la.
