Compare Roman Colisseum to Ancient Egypt Pyramids. What roles do these structures have beyond their specific intended use? you can answer by...

I really don't see the two structure as comparable since
their purposes were entirely different.

Conventional
thinking is the the pyramids were built as tombs for the pharaohs.  If this is true,
then they serve a religious purpose since the pharaohs were consisdered
gods.

According to Sumerian scholar, Zecharian Sitchin.
they are part of a complex guidance system for the gods aka the Anunnaki.  His theories
are based on ancient Sumerian texts which predate the
Bible.

The Roman Colosseum, on the other hand, was built
for entertainment.  Granted, theatre grew out of religion, but the Romans built theatres
for that purpose.  The purpose of the Colosseum was pure entertainment like gladiatorial
combat, chariot races, and sea battles.  In the Colosseum, death was real since slaves
and captives were expendable.   Ultimately bread and circuses were a way to keep the
people from rebelling against an oppressive system.  The government fed them cheap wine
and bread while they "entertained" them to take their minds off of real
problems.

Ultimately it all backfired with the Christians
who met death with dignity.  Those watching began to wonder if this new religion might
be their answer also.  So, perhaps with this connection they are comparable, but it is a
stretch.

The pyramids celebrated life beyond this earth and
for the most part the Colosseum celebrated death.
