the interior of the arena also eliptical, is 74 by 44 meters and surrounded by a high base wall.
the steps even today have a capacity of 25,000 seats. the spectators could get to the seats through many points of access.
only a small part of the external wall, which is divided into three orders of stone arches, has come to us; but it is enough to show the originality size of the monument.
