Building the Impossible: Temporada 3, Episódio 4

3 - 4: Beachy Head Lighthouse

Rob Bell heads to England's south coast where he explores a trio of lighthouses built to protect vessels on the M25 of the high seas. At Beachy Head, the presenter learns about an 18th-century vicar on a mission to save more than the souls of seafarers. Rob also experiences gravity-defying Victorian innovation and discovers the genius way 20th century engineering rescued a lighthouse from plunging into the sea.
