1st century BC Villa di Publio Vedio Pollione built by the Roman Knight Publio Vedio Pollio.


Grotta di Seiano (Cave of Seiano) is despite the name not a cave at all, it is an 800 m long Roman tunnel which crosses the hill of Posillipo.

There are two different visits, an unguided but "accompanied" visit and a guided visit. The site may not be visited self-guided, probably to protect the site from damages, unintentional or intentional. On the guided tour, the guide will explain the background of the remains and related historic events. The other tours are almost self-guided, there are no explanations, the visitors are accompanied by a representative of the association. The unguided tour is free, and while there are actually no explanations, its nevertheless necessary to keep together in a group and follow the orders of the non-guide. For both tours, it is recommended to make an online booking, especially in times with more visitors, on weekends and during the holiday season.
