Several mysterious metal structures have sprung up in different parts of the world in recent weeks, sparking speculation on social media about their origin.

Another monolith, this time a golden one, has appeared near Chia in the Colombian department of Cundinamarca, Newsweek reported, citing local media reports.

Videos and photos emerged on social media, showing a mysterious metal structure standing in the field close to a river. 

The author of the video invited people to see the monolith "before it is covered in graffiti or conspiracy theorists arrive".

Another person, who made some photos, says that this monolith differs from those which earlier appeared in Europe and the US.
