We are here in section 50: one of the two passageways through which people could enter
the Arena. The two passageways are found on ancient plans and texts.
You have to imagine that here the level of the floor was higher than it is today.
There was no staircase.
There must have been a gradual slope leading up to the upper corridors.
That is attested to by the openings.
Archeology has indeed proven that there were no houses here.
However, there were openings that gave access to the adjacent parts.
Like this door. Its doorstep
is at a much higher level. We no longer have access to it.
It must have opened up to a room, perhaps a guard post
or a dwelling… Unfortunately we don't know anything because it has disappeared.
This door is rather old, it has a small opening.
Next to it, there's another door that is a bit more recent.
It was closed off and the wall was redone, certainly a long time ago.
We think that one dates from the end of the Middle Ages,
while the other is from modern times.
