The
two revolving bridges stayed near the entrance corridors,
fauces, situated externally of a curvilinear entrance
resting on fluted columns ionic. On the island the small
inner space is optimally utilized: has been created a
domus with the typical outline, with entrance hall, triclinio
(the room for the lunch), cubicula (bedrooms), latrina
and also small thermes.
In fact it's a residence in miniature, theoretically inaccessible
from the outside, destined to the emperor's retreat and reflection:
he loved to swim in the channel, going through it more times.
The building is exemplar for its technical innovations: the continuous succession of straight and curves lines, the particular height of the columns and the trabeations, the effect played by the light and the refraction in the channel of the light architectonic elements, create an absolutely particular spaces and scenic effect. The singularity of this structure, its same conceptual value of "island", the wealth and the cure for the details, let's imagine the Hadrian's direct participation to the plan of this building.
