Cities have been built underground through the ages. They are usually dug underground to protect, but they can also be used as places for living and working. The idea of underground cities can be traced back to Ancient Era Europe or the Middle East. They could have been constructed to provide a refuge, mausolea, or storage rooms. They may also be used to provide transportation, especially in cold climates.
Underground cities are a network of subterranean spaces connected by skyways or tunnels. They may provide transportation or access to stores, restaurants or other activities. They could also be used for storage and defense against natural catastrophes. While some underground cities are accessible to the public, others are closed to the public.

FAQ
How does the brain control the functions of your body?
The brain sends messages to other organs and muscles to ensure they work together. Your body's functions are controlled by your brain. It tells you your stomach to digest food; your lungs to inhale air; and it tells you your arms and legs how to move.
Your brain is composed of billions and billions nerve cells, connected in groups called neurons. Neurons communicate by sending electrical signals, called action potentials, on axons. Each neuron is covered by a cell membrane. Channels within the membrane allow ions such potassium and sodium to enter and leave the cells. The electric charge that causes the neuron's fire is created by ion movement.
Neurotransmitters, chemical substances that are released when a neuron fires. Neurotransmitters can bind to receptors at the second neuron. They open ions channels, allowing ions to move in and outside of the channel. As a result, second neuron fires as well.
Neurotransmitter production occurs when a neuron in the presynaptic receives an impulsive signal from another. The impulse travels along an synapse between the neurons. The transmitter binds to the receptors on the postsynaptic neural cell, which triggers the firing of that neuron.
Neurotransmitters are important for communication within the nervous system. They coordinate brain activity among different parts.
What is the most secretive place in the world, and why?
This question might surprise you. It might even make you uncomfortable because it challenges our perception of reality and how we live. However, there's a reason for this place to exist. It's not what we would expect.
It was known as the City of God to the ancient Greeks. In the Bible, it was known as the City of Destruction.
It's known in India as Kashi (Kashmir). In Russia, it's called Novgorod.
However, in America it is called The Town that Disappeared.
One tiny town in western New York State lost its 1,200 inhabitants without trace. No bodies, cars, houses, nothing was left behind except a road sign pointing to its former location.
This little town disappeared, leaving no clues about where it went or when. Some claim the earth swallowed it. Others say it was destroyed in a meteorite collision. Some believe that it was taken by aliens.
Regardless of what happened, residents of this once-thriving town are certain that their town won't be forgotten forever. They had just moved from one town to the other.
You can even track the disappearance of Zugspitz on a dedicated website.
Then, where is it? It's actually in Switzerland!
You can find Zugspitze at the border of Austria and Germany. A huge lake, Lake Zugspitze, is located just beyond the summit.
It has always fascinated and astonished me to see how many towns have vanished but still exist. What is the difference between some towns that disappear and others that survive? I decided that I would investigate.
I was interested in learning more about these mysterious towns that are disappearing. What causes a community to disappear? What makes a place disappear?
It turns out that there are several theories about the phenomenon of vanishing towns. One theory holds that a town disappears if all its buildings are demolished. Another theory holds that the town simply relocates to another location. A third theory claims that the town never existed at all.
The fact is that hundreds of towns all over the world have been swept away by the ground, despite theories to the contrary. This video examines the past and present status of these areas.
What is the most mysterious location on Earth?
Antarctica is considered the most mysterious area on Earth.
What is it that makes this place so interesting? Because it is unlike anything else on Earth.
It is very remote and isolated. However, there's more to this location than meets the eye.
This natural wonder is also home to some of the strangest wildlife species.
Let's find out how this mysterious destination became so famous.
Antarctica, The South Pole
Antarctica is named for no one. Some say it means "land on ice." Others believe it derives from Greek mythology.
In ancient Greece, Antarktis was the name given to the island where Zeus' twin brothers were born. According to legend, one twin was born in winter. This is why the word "antarctic" was chosen.
Others believe that the name comes from the Greek words anti meaning against and tropos meaning to turn. This would mean land turned away from the sun.
Whatever the reason, Antarctica has always held a special fascination for people.
It is the highest, coldest, windiest, dryest, and most populated continent. Because it is so cold, there aren't any trees, plants or animals.
Yet, this frozen wasteland is alive.
Here are about 90% of all the living creatures on Earth. It is home to approximately half of all world's animal and plant species.
What is it that makes Antarctica so unique? Here, water freezes and becomes ice instead of evaporated into the air.
This causes large ice masses to rise above the ground.
These glaciers cover more than 80% of the continent. These glaciers are getting larger each year.
So far, the Antarctic ice sheet has grown 60 feet since 1960.
If the melting continues, sea level could rise up to 200ft. This could lead to widespread flooding.
This does not mean that everyone is wrong. Some scientists believe that global warming can be beneficial. They believe that global warming will lead to melting ice sheets faster and floods that can flush toxic chemicals out of our soils and bodies.
But others warn that this theory sounds like a plot from a science fiction movie.
What are some dark secrets in Hollywood?
Hollywood is filled secret societies. There are secret societies that are more cult-like than others. They have members who follow specific rules and rituals. While some are clubs for those with similar interests, others are not.
There are other nefarious entities that have a significant influence on the industry. These include companies like the MPAA ("Motion Picture Association of America"), which determines film ratings. The RIAA ("Recording Industry Association of America") sets music licensing fees.
Numerous unions or guilds also represent producers, writers, actors, etc. Most major movie studios and television networks are owned by large corporations which own these various organizations.
It doesn't matter how secretive a group might seem, someone somewhere knows what they are doing. We shouldn't fear these people.
Instead, we should embrace these facts. Because they provide us with information that helps us make better decisions.
They can tell us which movies and songs are likely to be successful, as well as what books and novels will be most popular.
They are, in short, what help us choose what we will watch, read and listen too.
We can trust them so we can ignore their advice when it doesn't suit our taste.
We choose to ignore them and they become even more powerful. They are the supreme arbiters of taste.
They can be ignored if you don’t like what they have to say.
Let's take a closer look at some of the less-known, yet still very real Hollywood secret clubs.
And see why they're so important.
