I have been conducting a small amount of archaeology of the ruins site in my time there (unfortunately no digging or GPR).
As I'm sure you're all aware, there seems to have been some kind of battle or mishap occur at the site in the past. Many of the obelisks in the various formations have been knocked over, cleaved or melted:
I have mapped the various damage and marked it as red dots on the pics below (if a obelisk formation does not appear in the pics below it means it has no damage):

ok, I lied...there is also the damaged obelisk on the small landing pad that I thought I had incorporated into the above image but apparently not.

Also, it appears that a segment of the inner wall has been "rubbed out" during the history of this place:
The fact that the obelisks are overlaid on an area where it appears there was once a large chunk of wall, now removed, suggests to me that that wall and possibly the large landing pad to which it is connected pre-date the obelisks.
(yes I am a huge fan of Time Team).

This planet was under meteorite rain. You can clearly see that all of this damage to obelisks and walls and anything else was caused by meteorits)
