Long ago, the rock had three large holes. The sea waves cut through the stone over time. Two of those holes fell down. One fell in 1845. Now, only one big arch remains. This arch is very high. A small boat can pass through it at high tide. The rock is a home for many birds. Over 110,000 northern gannets nest nearby.

You can also see puffins and whales in the water. The rock is full of history, too. It has 150 types of fossils inside it. These are the remains of ancient plants and animals. The rock is very heavy. It weighs about 5 million tonnes. Wind and water change the rock every year. It loses about 300 tonnes of mass each year. Scientists think it will disappear in 16,000 years.
