Portus was protected by fire-fighters (vigiles), like Ostia. The place of discovery of inscriptions suggests that their barracks in Portus were to the east of the Episcopium (41). Soldiers from different Roman cohorts are documented. From the later second and early third century AD come three dedications to Fortuna Domestica Sancta and Hercules (Thylander B288, 289, 292), two of these for the health of the Emperor. A statue of Hercules was found not far away. A large gaming board (tavola lusoria) was also found.
