The argument that appeals most strongly to many in supporting the theory
that Sun Temple was a ceremonial building is the unity shown in its
construction. A preconceived plan existed in the minds of the builders
before they began work on the main building. Sun Temple was not
constructed haphazardly, nor was its form due to addition of one clan
after another, each adding rooms to a preexisting nucleus. There is no
indication of patching one building to another, so evident at Cliff
Palace and other large cliff dwellings. The construction of the recess in
the south wall, situated exactly, to an inch, midway in its length, shows
it was planned from the beginning.
We can hardly believe that one clan could have been numerous enough to
construct a house so large and massive. Its walls are too extensive; the
work of dressing the stones too great. Those who made it must have
belonged to several clans fused together, and if they united for this
common work they were in a higher state of sociological development than
a loosely connected population of a cliff dwelling.
