Hidden From The World: These Are The Biggest Abandoned Places On Earth

Swallow's Nest Castle, Ukraine

You may think that why a castle from Game of Thrones made its way into this list, but that is not the case. Located on the Black Sea in Southern Ukraine, this astonishing castle is called the Shallow's Nest. A wealthy oil merchant built the castle in 1911.

By the way, a wooden cottage called "The Castle of Love" was built on the same spot before the Shallow's Nest. This stunning castle is built on top of the Aurora Cliff.
