Were the tombs and other structures originally sealed in with no path to the outside world? Were there other rooms accessible for rituals without archaeologists having to excavate tunnels in the modern day?
For the majority of the monuments that I worked on, they were ritually destroyed, buried, and built on top of -- with the Rosalila temple being the main exception. The tombs typically have some type of arch and the temple area and staircases are kind of built around or on top of them.
