On the flood, water funnels around the southern tip of Portland and meets the open Channel coming the other way, and the resulting churn rises in standing waves that have flipped fishing boats within sight of land. The Shambles - a long, shallow sandbank a few miles offshore - finishes the job for any vessel the race has already damaged. Three lighthouses are visible from this headland. The earliest one started warning ships in 1716. They were all built for the same reason: the Bill is, and has always been, one of the more reliable killers of ships on the English Channel.

Portland Bill: Pulpit, Crane, Coastguard

Wed, 20 May 2026 00:00:00 GMT

Photo credit Andy Potter, CC BY-SA 2.0. The Bill is more than its lighthouses. Pulpit Rock - a detached limestone stack carved deliberately by quarrymen to leave a single tilted pillar - juts up at the very tip, a famous photograph that has appeared on more Dorset postcards than perhaps any other view. The Trinity Hous...

Portland Bill: Strip Fields and Tidal Races
