Hexagonal pool built for Trajan
The Roman port Portus from the empire with the current view. The port was built during the reign of Emperor Claudius (41-54 CE) and was greatly expanded during the reign of Emperor Trajan (98-117 CE), to be complementary to the port Ostia.
It was located on the northern bank of the Tiber estuary to the Tyrrhenian Sea. The port covered 69 ha, had two long piers towards the sea and an artificially built island with a lighthouse.
Probably during the reign of Claudius, a 24 km road from Rome to the Port called Via Portuensis was also created. It ran through the modern mountainous region Ponte Galeria, and then a flat clearing.
In 103 CE Emperor Trajan added another port to Portus – a hexagonal pool with an area of 39 ha – which connected with the construction of Claudius through a series of channels.
