What is the largest underground settlement in the world?
Oh, that's good to know. Do you happen to know how long people have been living underground in Coober Pedy for?
People have been living underground in Coober Pedy for over 100 years. The first dugout homes were built in the early 1900s by miners who were looking for a way to escape the harsh living conditions on the surface. Today, many of these original dugouts still exist and are still being lived in by residents of the town.
