Despite technological developments and the ease they provide, some people continue to rely on antiquated equipment.

Take, for example, this cave made by a 67-year-old man who demonstrated that age was no barrier to completing such a huge endeavor.

Using basic home goods such as a cart and shovel, he worked tirelessly on his project, earning relatively little in the process. Despite a lack of formal education, he believes that others would appreciate his handiwork.

The man began excavating his cave in 1987, never expecting it to become as well-known and visited as it is now, with numerous things adorning its walls. The magnificent beauty of Ra Paulet’s tunnels makes determining their value impossible.

To date, the man has built 14 caves and is currently working on his 15th, which he claims will be his most remarkable. Watch the video below for more information.
