Hey guys, today I am going to show you a very strange ancient site in India completely built underground. This site is shrouded in mystery - We don't know who built it, why it was built and how it was built. Experts believe it is at least 1200 years old, and some locals even say it is 5000 years old. The shape of this structure is mind boggling. When you see it from the air, it has a very unique shape, like an elaborately fashioned key hole.

I first visited this site in the last week of march and I was amazed by the outer view and immediately proceeded to go down the steps to see what is underground. As I went in about a dozen steps, I realized that the entire structure is filled with water, from a certain point onwards. I was not able to see the floor or what is inside because of the water and the water is heavily contaminated. However, I was able to see Hindu religious signs painted inside, and I decided to go back up to the ground level, and see if I could get another view. On top, there is a metal gate which is permanently locked. I looked through it and I could see some amazing carvings right in the middle of all the water. The pillars are partially submerged under water but exquisitely carved. At this point, I was dying to go inside but it is impossible to get in. Luckily, locals told me something very interesting:

Every year, locals pump the water out on a certain date, and clean up this site for a religious event and that event will be held today, the 19th of April . So I decided to wait until today, so I could finally find out what is inside.

When I entered this site today, I immediately felt a difference. I could see a large pump on site, and the ground is dry, which means the water would have been pumped out a few days ago. I could also see fresh paint on the carvings of the entrance. As I entered through the steps, I had no idea what would be inside. Is it a large temple with many statues of Hindu Gods? Or Would this be some kind of an underground palace with elaborate rooms? Remember, ancient sites in India always surprise you, you should never come in with expectations. The steps which go down reach a low point, then there is a small elevation, and then we enter into a chamber. This immediately leads to what looks like a square hole in the very center. The interior design is mind boggling and the beauty of this entire structure is beyond words, it makes you wonder if it was built by Gods themselves. Looking at the interior, I realized right away that this is a very strange structure - it is not a Hindu temple, it is not a palace, we simply do not know why this was built. Some will definitely claim that this is a water well, but this makes no sense at all- why does a water well need such an elaborate design and extraordinary carvings? Why create them at all, as they are going to be underwater most of the year? It has some other purpose, the entire structure was made for some scientific reason, a reason which we are not able to understand. Why did they have to build it in such a unique shape? It is even visible from the satellite and the shape immediately catches your attention. Is it a coincidence, or was it meant to be recognized from the sky?

Why is this structure so mysterious? No one knows its original name and it has at least half a dozen nick names among locals. What is interesting is that, this square in the center is called Karungkuzhi which literally means "Black Hole" in Tamil language. What is even more surprising? Locals believe that this hole has a secret doorway to a divine world, it could take you to a parallel universe. Did ancient builders create some kind of a doorway to access a parallel universe? Is this why this structure was built?

Sitting in this place, looking at the black hole, I wonder if there could really be a doorway inside this which leads somewhere. Locals vehemently insist that it does have a doorway and some claim to have even seen it. I have shown you so many different ancient sites, many of them go underwater and locals always claim there is a secret entrance inside. Is this site also going to be yet another one, where I simply theorize there is a hidden doorway? No! today, I am going to show you that doorway!

Look carefully at the inside walls, you don't see anything on this side, but on this wall you can clearly see the opening - this is the top of the underwater doorway. You can even see the shadow of it being cast on water.
