Aside from animals, Darwin’s Arch is one of the most famous, and most photographed, things on the Galapagos Islands. As of May 17, it has permanently changed a little: The arch collapsed into the ocean, leaving behind two solitary unconnected pillars.
In a tweet, the Ministry of Environment for Ecuador reported that the cause of the collapse was erosion — a natural process and not one connected to human interference or overtourism. The huge rock formation (141 feet high, 230 feet long, and 75 feet wide), takes its name from the iconic naturalist who found much of the inspiration for his theories of evolution from his travels around the Galapagos Islands.
