The Imperial Ports of Claudius and Trajan belong on this map as a distinct imperial harbor complex, not as a second label for Ostia Antica. The visitor entrance is mapped at Via Portuense, 2329, 00054 Fiumicino RM. Because the pin marks that entrance rather than the landscape centroid, map users should use it to identify the access location, not to estimate the whole extent of the site.

A visit is framed at 90–120 minutes. The practical contrast with Ostia Antica is pronounced: public transport is described as awkward here, while taxi or car is more practical. That makes this Place a deliberate transport choice, even though it forms part of the wider Ostia park system.

The supplied information says to verify current combined-ticket and opening conditions. Do not assume that belonging to the Ostia park system automatically means identical entry arrangements to Ostia Antica. This pin is for visitors specifically seeking the imperial harbor complex at Fiumicino and prepared to check how its current access and ticket conditions operate.
