Darwin’s Arch, a rock formation south-east of Darwin Island in the Galapagos archipelago, has collapsed due to natural erosion, Ecuador’s environment ministry said.
Images on the ministry Facebook page on Tuesday show two rocky pillars left at the northernmost island of the Pacific Ocean archipelago, which lies 600 miles (1,000km) off South America.
The post said: “This event is a consequence of natural erosion. Darwin’s Arch is made of natural stone that at one time would have been part of Darwin Island, which is not open to visits by land.
“This site is considered one of the best places on the planet to dive and observe schools of sharks and other species.”
