This may be mod related, but I don't have any mods that affect the city layout for any city in Skyrim. It appears the rock terrain has been smashed together some how. The terrain texture around this flickers and stuff as well. Here are two screenshots taken from the north and south side of the Temple structure in the middle of Markarth.

I also have other problems that I've posted in this forum that are terrain related. Any help on figuring out what is causing this would be great. I am stumped.
