Not sure if this is of any interest.
On the right and lower side of the "compound" the walls appear to have collapsed. With the large metal barriers lying flat.
Not sure what to make of it, no atmosphere = no wind?
Erosion?
The lower one seems much more pronounced. And assuming the metal parts were spaced evenly seems like it might have moved quite a way from its original position.
No collapse metal barriers elsewhere, just right lower side.
Meteor impacts, stellar winds, plate tectonics. Dust storm and/or quake from a large impact.
