Ramblers are being warned after a large section of the south coast's highest sea cliff - part of the World Heritage Jurassic coast - crashed into the sea.
Golden Cap is part of the World Heritage Jurassic coastline
Coastguards alerted police of a major landslide at Golden Cap Hill, near Bridport, Dorset, on Tuesday evening.
Other sections of the 627-feet (191m) cliff have been left in an unstable state, a Dorset Police spokesman said.
"This was a substantial slide, about 75 feet in height and affecting about 500 feet along the cliff face," he said.
"Fortunately no one had been injured or trapped by the fall.
"The area remains very unstable and is likely to have further falls - I would ask that people avoid the beach area underneath Golden Cap and the cliff-edge."
The cliff face, a local landmark, is part of the Jurassic coastline, made a World Heritage Site by the United Nations' cultural committee in 2001.
The site stretches 95 miles (150 km) from east Devon through Dorset.
