Horrea were erected along side III of the hexagon, to the south-east of the Internal city wall (24).
In this area one funerary chamber and two funerary enclosures were found in 1924 by Calza. They were made in the second half of the first century by people working in the harbour of Claudius. An inscription informs us that one of the people buried here or nearby was Titus Flavius Ingenuus, an Imperial freedman and tabularius Portus Augusti, i.e. in charge of archives.
