A mysterious monolith covered in coordinates has appeared in Adelaide after similar structures appeared across the US and Europe.
The latest monolith is a three-sided, three-metre-tall silver structure that was first sighted near the Seaford Train bridge in Noarlunga in Adelaide’s southern suburbs at 6pm on Thursday.
Coordinates on the structure point to various locations across the globe, some of which are landmarks and some of which are seemingly random.

The top coordinate is a brownstone building in Brooklyn, New York, while the second location is the uninhabited island of Managaha in the Northern Mariana Islands, near Guam, in the Pacific Ocean.
Lastly, the bottom coordinates mark The Sphinx in Egypt’s Al Giza Desert.
The monolith is located in Noarlunga, which is part of the City of Onkaparinga.
An Onkaparinga Council spokesman said he was only made aware of the structure after being contacted by the media and was currently investigating its origins.
The Adelaide sighting comes after two monoliths were spotted in Poland on Wednesday.
One was found on the banks of the Vistula river in the nation’s capital Warsaw on Wednesday afternoon.
Prior to this, another was spotted in the southern city of Kielce at a former quarry turned into a nature reserve on Wednesday morning.
The first shiny pillar was spotted in southern Utah on November 18 by baffled locals and news of the object quickly went viral around the world.

Some observers pointed out its resemblance to the avant-garde work of John McCracken, a US artist who lived for a time in nearby New Mexico and died in 2011.
But McCracken’s representatives have given ambiguous and at times conflicting responses to this theory, prolonging an international guessing game that intensified further with the monolith’s sudden removal on Friday.
The Most Famous Artist, also known as Matty Mo, is also thought to have been behind some of the monoliths that appeared in the US.
The monoliths have sparked comparisons to those seen in the Stanley Kubrick film 2001: A Space Odyssey.
Others have since popped up across the US, as well as in Colombia, Romania and the Netherlands.

Prior to the Polish structures, a monolith appeared on the top of a hill in Glastonbury in the UK on Wednesday with the words ‘Not Banksy’ etched onto it.
Walkers discovered the large silver structure on top of Glastonbury Tor – an ancient hill linked to King Arthur and celtic mythology.
It was believed the monolith had been placed there overnight – but was felled by a gust of wind.
The shiny triangular pillar featured a stencil drawing of a rat, similar to the style used by street artist Banksy.
Prior to that, another popped up on the Isle of Wight on Sunday, drawing a crowd of locals looking to take a selfie with the unusual object.
Designer Tom Dunford later admitted that he installed it as a tribute to others around the world.

Structures also appeared this week in a small German town, a forbidding Spanish hillside and a muddy potato field in Belgium.
One of the bleak silver columns showed up in Sulzbach, Germany, overlooking a field near a shopping centre.
Another was by the ruins of an old church in Ayllon, Spain, where local authorities warned people to steer clear of the dangerous slopes – while a third was spotted on Tuesday in the Flemish village of Baasrode.
While the people behind some of the mysterious structures have been revealed, for the most part their origins remain a mystery.
Theories abound, including suggestions that artists, aliens or savvy marketing executives.
The fact that some of the monoliths were quickly removed has only added to speculation about their potential origins.
