That has always been my understanding. From a purely engineering point of view, are there any known prehistoric structural techniques that could have achieved the façade we now have?

Yes, similar walls were found at Petit Mont, Gavrinis, Barnenez etc. A good intact section of similar walling can still be seen at Baltinglass Hill.
