There appears to be another mosaic floor UNDER this one. Amazing. And they are still uncovering more. That building isn’t going to built any time soon.

The ancients had zero qualms about building their stuff over the top of other, older stuff. What’s left of the Theatre of Pompey, in Rome - where Julius Caesar was murdered in 44 BC - is currently being excavated; it is located directly under a modern street.
