National Underground America Day – May 14, 2025

National Underground America Day on May 14 revolves around cherishing the concept of societies living underground and thriving. Yes, we don’t only have to live on top of land — there is a lot more going on underground than you can imagine. Here is all you need to know about celebrating National Underground America Day.

History of National Underground America Day

Though the concept of living underground existed before, the topic gained national attention after Malcolm Wells founded National Underground America Day in 1974. Wells was an architect, writer, lecturer, and thought leader who worked in the architecture and design industry for years. After a while, he realized that Earth will only thrive once it’s rid of industrial plants. Since then, he began his mission of spreading awareness about underground living and the numerous benefits it holds. In fact, he made it a point to create an underground abode for himself, as well as his very own earth-shelter office space.

Malcolm Wells, who is also recognized as the “father of modern earth-sheltered architecture” today, endorsed underground living until the day he passed away. However, even after his death, his legacy remains and National Underground America Day is celebrated yearly to pay tribute to the thousands of people living underground in numerous parts of North America. Yes, believe it or not, many individuals prefer living underground than on top. This is because it has numerous advantages for human life as well as the health of the planet. According to Wells, building homes under the earth’s surface is “gentle architecture” — since it does not have a negative impact on the landscape.

National Underground America Day is celebrated to cherish the underground way of life, its architecture, and the numerous benefits that subterranean living has for the Earth. Though thousands across the globe are living underground, will this trend become more common in the near future?
