The PRIUS is funded with €13,728,314.24 from the PR Campania ERDF 2021–2027 (Priority 5, Action 5.1.1); to obtain the 20% bonus, 70% of the funds must be legally committed by 31 December 2026. The goal is a town that is «more connected, inclusive, sustainable and attractive», stitching sea, town and Vesuvius back together.
The D.O.S. links the PRIUS to complementary investments already under way: the new waterfront, the expansion of the Herculaneum excavations with the Packard Humanities Institute, and the university campus at the former Officine Fiore. Close by, the restoration of Villa Favorita is in progress.
