Another mysterious monolith has appeared in on the Romanian hillside after a similar structure found in the remote desert in Utah was removed by an “unknown party”.

The silvery triangular monolith was found in Utah on November 18 before vanishing on the 27th.

Now, a similar structure has been found on Batca Doamnei Hill in the city of Piatra Neamt in northern Romania last Thursday, prompting the local mayor to make a statement.

“There is no reason to panic for those who think there is still life in the universe,’ wrote Andrei Carabelea.

“My guess is that some alien, cheeky and terrible teenagers left home with their parents’ UFO and started planting metal monoliths around the world. First in Utah and then at Piatra Neamt. I am honoured that they chose our city.”

“Beyond the conspiracy theories that can be tempting, I’d like to see this randomness as further proof that our city is special. For the earthlings and (maybe) not only,” the mayor added.

He jokingly said that he’d appreciate it if an application for a building permit was submitted prior to the structure’s appearance, and hopes that the monolith would attract more tourist.

While both structures are about the same height – around 12 feet high – the monolith found in Romania is covered in looping markings.

It was found near a well-known archeological landmark called the Petrodava Dacian Fortress, a fort built by the ancient Dacian people between 82 BC and AD 106.

Meanwhile, the monolith in Utah mysteriously disappeared, with officials stating that its removal was nothing to do with them.

“We have received credible reports that the illegally installed structure, referred to as the “monolith”, has been removed from Bureau of Land Management (BLM) public lands by an unknown party,” the Utah Bureau of Land Management said in a statement.
