Was messing around with a mod I'm developing when I found this. At first I thought it was just a big ancient city, but there's two monuments (look closely at background of the first photo). Structures usually break when placed next to each other like this, but there's no overlap so it looks completely intentional. Confirmed the seed works in vanilla as well.
