Mysterious markings of extraterrestrial origin have appeared on Broad Haven beach in Pembrokeshire, one of the UK’s most renowned UFO hotspots — just in time for Halloween. The cypher, etched into the sand by Beavertown Brewery, has surprised locals and visitors alike with its ancient hieroglyphic style and cryptic message spanning the shoreline.

When observed closely, the mysterious sand art reveals a central cypher code written by Dr. Jo Melville from MIT. Beavertown Brewery is encouraging everyone to put their decoding skills to the test this Halloween, by attempting to solve the hidden code in the extraterrestrial beach markings.

Dr. Jonathan Melville said: “Ancient cultures used circular symbols like Norse runic circles and Hindu mandalas, but some elements in this design are more modern. The ancient Celts had no knowledge of computer structures, nor did they require them, which is why this design seems of non-human origin. This code is for those who possess a deep curiosity to unveil extraterrestrial messages — only the truly intrepid would decode its secret meaning.”

The impressive artwork, with a 6M wide skull at the centre, was uncovered shortly after the launch of the brewery’s otherworldly short film Flightmare, which follows an intrepid, dimension-bending plane journey through the Bermuda Triangle. Watch here.

The brewery has also commissioned research to uncover intriguing insights into the UK’s thoughts on alien life this spooky season. Turns out that a recent study of 2,000 adults found that almost half of Brits (42%) would try to communicate with aliens if they ever landed on Earth. Now they have the chance to.

Some people believe that mysterious symbols and patterns may not be the only things attributed to alien visitors — one-fifth believe that the Bermuda Triangle might have been created by extraterrestrial life forms. Additionally, more than a third (31%) hold the belief that UFOs played a role in the construction of the Pyramids of Giza.

The research also revealed that 56% of adults think that it’s likely that the government is hiding the fact that aliens exist.

Reasons for believing in alien existence include thinking the universe is so big there must be other life forms (86 per cent), while a quarter based their views on news stories. Almost a third (29%) believe more in extraterrestrials than ghosts.

Tom Rainsford, Beavertown Brewery’s Marketing Director, said: “Pop on the TV or check your socials, it seems everyone is talking about aliens and UFOs. So it’s not surprising that almost half the UK say they’d try and communicate with an alien if they ever came across one. You would, right? Just imagine the questions you’d want to ask. At Beavertown we are big fans of all things extraterrestrial, so to celebrate Halloween and the launch of our new short film and graphic novel ‘Flightmare’, we thought what a better way than to try to see, what’s really out there with a unique extraterrestrial sand message.”

Beavertown fans keen to crack the code hidden within the cypher will be in with the chance to win one of ten £100 vouchers for Beavertown beer and clothing. Punters can type their answers into the form here, where the brewery will also release three clues over the next week in the lead-up to Halloween. Ts and Cs here.
