The Colosseum (or Flavian amphitheatre) measured 527 m in circumference and 57 m in height,
and was slightly elliptic. It had four levels, of which three levels of arcades.
To protect the audience against sun or rain, one could
draw a linen (Velum) awning,
that can be guessed rolled on the edge of the roof, which would cover most of the seats.
No doubt that this monument is one of the most impressive in the antique world.
The
interior was just as fascinating.
