The man who discovered this artifact was hiding in a cave in the Tatra Mountains in Slovakia, and subsequently saw a tower-sized artifact, shaped like a cylinder, embedded in the rock. The intelligently designed structure is many, many thousands of years old. The report mentions polished walls, shafts, strange substances on them, and even a warm wall with a humming like a turbine heard behind it.
What impressed researchers the most was his report of stalactites and stalagmites in all the passages, blocking his way and scratching him. He had to break off some big chunks to pass. Now, a carstic structure like a stalactite grows about a centimeter each century. Therefore this structure is believed to be older than any known civilization. He also discovered some bear bones in there, where no bear could fit. If true this could be the strangest artifact ever discovered.
