Unlike the previous metal monoliths, this version is wooden and painted silver and was set up outside of Canopener Labs, a business near the San Antonio Airport, KSAT reported.

It’s far from other worldly. Images on social media show a group of people installing the makeshift structure late Thursday night, WOAI reported.

It is the third copycat monolith structure to appear since a team of biologists counting bighorn sheep discovered the first metal structure on Nov. 18 in a southeastern Utah desert. Satellite images indicate that it was installed sometime between August 2015 and October 2016. It was removed Nov. 27 by a group that said “Leave no trace.”

Its appearance led to international interest and the creation and discovery of a slightly similar structure in Romania. The poorly crafted pillar appeared Nov. 27 as a prank in the town of Piatra Neamt but disappeared four days later.

A 200-pound metal structure was found Wednesday atop a hill in Atascadero, California. However, it was toppled early Thursday morning and replaced by a wooden cross by a group chanting “Christ is king.”

The monolith structures are all believed to be pieces of art, although the creators and installers of them still remain unknown.
