Bergen, Norway is often called "the city of the seven mountains" due to being surrounded by, you guessed it, seven mountains. However, situated high in the foothills is a strange-looking hole, perched on the edge of a cliff. It's impossible to walk by something this bizarre without noticing it.
Imagine that you were walking in the middle of the woods and you found this. What would you do? Would you dare to go inside to see where it leads?
The hole is obviously man-made, but the way it's designed makes it look like the area around it is being sucked inside.
The structure was actually built by an architect named Espen Folgerø and his students at the Bergen School of Architecture. It is called the Tubakuba Mountain Hub.
The views are gorgeous, but it also looks a bit scary.
Folgerø works with the firm, OPA Form, and built the structure to appeal to families with children. He felt it would allow more kids to experience a night or two in nature.
The biggest design challenge was shaping the wood.
It was only possible to shape the hole by making the wood wet enough that it would bend without cracking. The final product is 95 percent wood.
The hole is the most unique entry way I've ever seen. It's large enough for children to walk through, but adults would likely have to crawl.
The hole leads to a 150-square-foot interior.
The inside is beautifully designed, with smooth, curving wooden floors and walls.
The view overlooks the city of Bergen and is absolutely breathtaking.
There's no electricity, but a small wood-burning stove provides heat for occupants.
The overview of the floorplan reveals how the inside is just as clever and unusual as the doorway that leads to it.
