Since 2017, the University of Huelva, in collaboration with the Archaeological Park of Ostia Antica, has been developing a research project on one of its interior piers, the socalled lantern. Said east-west structure or pier is the best example of its category in the port complex. With a length of about 150 m. the latest research has provided numerous and interesting data on its architecture and diachrony, highlighting significant phases in its evolution from its construction to its final abandonment in the beginnings of the Middle Ages. Therefore, the results presented here represent a significant novelty in the general knowledge of Portus and in that of its docks in particular.engAttribution 4.0 Internationalhttp://creativecommons.org/licenses/by/4.0/PiersDocksNavigationPortusOstia Anticajournal article10.1007/s11457-023-09360-9open access5505.01 Arqueología
