Following the disappearance of the strange monolith found in the Utah desert which vanished as soon as it had been discovered, another similar structure has now been located in northern Romania, adding even more mystery to the objects.

The object has been found close to an important archaeological site outside Piatra Neamt in the northern part of the eastern European country. Appearing identical in structure and size, around 13-feet tall, the Romanian version features concentric circles, and like the Utah one, it stands on an illegal piece of land.

Many speculate it is likely the work of a prankster inspired by the science fiction novel 2001: A Space Odyssey, or an artwork by minimalist artist John McCracken. Or a Westworld leftover prop. Or perhaps aliens. Who knows.
