A few kilometers from Rome the Oasi di Porto offers a picturesque natural setting, fascinating traces the history of the territory of the River Tiber, near its outlet to the sea.
The OASIS stretches around the lago di Traiano. The basin, of perfect hexagonal shape, of 33 hectares, represents as a work of great historical value, an important stopping point for migratory birds on their long haul water from the Mediterranean regions and Northern European ones, where nesting and vice versa.
The distinguishing feature of the Oasi di Porto is the old dock built by Emperor Trajan (100/112 ad), replacing the existing port of Claudius, open to the sea and is no longer usable for cover-up.
It is an imposing, vital for supplies of Imperial Rome, with all the port facilities (warehouses, docks, etc.), as well as civil and religious buildings. After the fall of the Roman Empire and the barbarian invasions in the middle ages, the territory is invaded by the waters that extended malarial marshes formed. The intervention of Popes Pius II and Sixtus IV earned not for rehabilitation, while some Roman patrician families, in more recent times, attempted such a feat (Panfilo di Pietro, Pallavicini) without success.
After the purchase of the estate by the Prince Alessandro Torlonia (1856) reclamation and colonisation of the territory were finally implemented by his successor Prince Giovanni Torlonia, who also worked on the recovery of archaeological remains in the former State of disrepair (cfr. G. Lugli – G. Filibeck. The port of Imperial Rome and Agro Portuense, 1935).
