A mysterious shining monolith with strange engravings has vanished after appearing in a field in Australia.
The three-sided, three-metre-tall structure had been erected at Seaford Train Bridge at Noarlunga in Adelaide's southern suburbs, South Australia, on Thursday.
Though by Sunday the strange object had disappeared and been replaced with three metal posts.
Similar structures, often with a series of coordinates leading to landmarks, have appeared all over the world in recent weeks.
