i feel like it's a tower that would have been built by a excavation team or something xD same with the wooden structure in the bottom left w/ ropes and shovelsThat tomb is weird, the identity of it is all messed up. I'm guessing you enter that area from the left after exploring an area. Is it it meant to be an ancient place and you come across the sarcophagus? If so what is with the wooden tower? You might need to explain the story of that a bit better.
