First human monument: The Bailum Observatory

Religious event

The approximate date that the first ever human structure (and perhaps the first structure ever) was built.

This structure, similar to Stonehenge, was presumably built to observe either natural phenomena or old activities of the gods. It can still be visited at Steirvem today, though it no longer has its original clean visage. The different doorlike structures line up with the Orphi Gap, the Serpent in the sky, and the direction the Snow Rocks were expanding at the time. In the modern era, The Serpent has faded and no longer lines up with the observatory.
