The Regenwurmlager, which literally means Camp Earthworm, is an extensive underground fortification area constructed by Germany in 1920s-1940s, now in western Poland, near the city of Międzyrzecz. It was a system of underground bunkers interconnected by tunnels and corridors of total length over 100 km. In 1945 it was abandoned by the German troops retreating without significant fights.

For only $17.5 million, this bunker in Southeast Georgia called “The Facility” could be yours to own and it would be a great investment for anyone who fears the apocalypse.

Beer thieves are a plague that we must all fight.

Girard B. Henderson decided to build this impressive underground home in the 1960s and it is pretty cool to see inside.

These condos are all equipped living spaces that have been built in the event of an apocalypse and some of them are pretty fancy.

This 5,000 square foot subterranean villa was built to withstand a nuclear blast and is located in a 15,2000 square-foot bunker. This home has a heated pool,  sauna, bar, dance floor and putting green amongst other things.

This house in Las Vegas was constructed during the Cold War as protection from a nuclear apocalypse. It comes complete with an underground lawn, BBQ area and pool amongst other things and is now on sale for $1.7 million.

The Cu Chi tunnels are located in the Cu Chi district of Ho Chi Minh City, Vietnam. They were used by the Viet Cong throughout the Vietnam War to carry out military campaigns and were the base of the Tet Offensive in 1968.
 

Construction continues on the Second Avenue Subway's future 86th Street Station. This photo shows the latest progress.
 

London underground signs that are truly bizarre.

Coober Pedy is a small Australian town with population of about 2,000 people. It is well-known as an underground town.

These are some beautiful images of Tokyo underground. Most cities have another world underground but none as so breathtaking as this. It looks like another dimension.

This spectacular dome with an underground tunnel is no longer in use, even though it sits on a privately owner estate. Built in 1890, the underground space was used as a ballroom and billiard or smoking room.

Tokyo underground system is a day-by-day insanity. Local residents and guests are often pressed against windows and other people. Pictures from the series “Tokyo Compression” by Michael Wolf perfectly document the real daily Tokyo subway atmosphere. I wouldn’t enjoy starting my day like this.

Pionen is an underground data center that belongs to the biggest Swedish internet service provider Bahnhof. It is located 30 meters under the granite rocks. It was built in a former bomb shelter, thus it can withstand a direct attack with a hydrogen bomb. Two Maybach MTU diesel engines from a submarine are responsible for backup power supply. Together they produce 1.5 megawatts of power. The entrance doors are 40 cm thick. The place is surrounded with the granite and it just mesmerizes with its beauty.

When you are in the subway, you can either read a book or ads or stare at amazing art. Personally I would choose the last option. Sadly, the subway in my city doesn’t have anything like what you will see inside this post.

Let’s take a close look at the New York City subway and its riders’ life underground.
