Bird’s eye view of another Stadium, built under the Emperor Domitian.
This stadium, also called
Hippodrome, is built between the Domus Augustana
and the Baths of Septimius Severus on the Palatine. It was actually a large pit
of 145 m in length, surrounded by porticoes

.
It is not clear whether this stadium was used for games reserved for the Emperor,
or was a garden and training field opened to the public.
You notice on the right side of the stadium (in the middle),
the semicircular exedra where the imperial box was.
