Ortli Villa is a Sansar Studios experience, a virtual museum exhibit of an ancient Greek excavation site in Crimea dating from the fourth or third century B.C. It would appear that the source mesh for this exhibit comes from an automatic 3D model reconstruction based on 400 photos in Agisoft PhotoScan, and published 3 years ago on Sketchfab. Regardless of where it came from, it’s an interesting exhibit and a good demonstration of how to display an archaeological site in a virtual museum setting. You can even take the stairs to the second floor to get an overview of the project!
