In September-November 2012, we carried out an archaeological sounding in the sector of the Oppian Hill park above the outer surface of Trajanic Galleries 20A and 20B. The study was aimed at understanding the external layout and construction features of the ancient vaults, with a view both to reconstructing the missing parts and to defining the new external protection system for the monument. Below we publish the preliminary results of the archaeological study.
In recent years, archaeological excavations have been undertaken in the Oppian Hill park above the Domus Aurea pavilion with the aim of testing rehabilitation and waterproofing systems for the ancient structures, in order to intercept rainwater and thus eliminate percolations inside the underground monument.
