The 2018 excavations provided new information about the use of the horrea in the imperial period between the 6th and 16th centuries A.D. Two rooms were investigated inside the horrea Vespasiani where a substantial stratigraphy relating to the post-antique occupation of the building was documented. Between the 6th and 7th centuries A.D., a production activity was set up here that produced a large amount of metalworking waste. This installation was obliterated by the deposition of three infant burials (7th-9th century A.D.) and was later buried below a substantial dump of material put down in relation to the construction of the Orti Farnesiani.
