1953. One-fifth scale models of the ships were built in the Naples naval dockyard and these, along with the remaining artefacts, are housed there. In September 2017 a panel made of inlaid marble and mosaic then in the collection of a private owner in New York City was rediscovered by the antiquities restorer and author Dario del Bufalo. Subsequently the New York County District Attorney's Office seized the artefact which was confirmed to have come from the Nemi Museum, and to have once decorated the floor of Caligula's ship. It had been bought by American antique dealers Helen and Nereo Fioratti from an aristocratic family in the late 1960s, and used since then as the surface of a coffee table in their home. In October it was officially repatriated to Italian authorities. Project Diana Photographs, the drawings made for the Italian Navy survey, and those made by the archaeologist G. Gatti, survived, allowing reconstructions to be made of the two ships. In 1995, the Association Dianae Lacus (Lake of Diana Association) was founded to preserve the culture and history of the Nemi Lake area. The Association initiated Project Diana, which involved constructing a full-size replica of the Roman prima nave (first ship) of Lake Nemi. Since no record is known to exist of the shape and size of the buildings and temples built on the deck, the replica was to be constructed to deck level only and when completed would be moored on the lake in front of the museum. On 18 July 1998, the town council of Nemi voted to fund the construction of the forward section and work commenced in the Torre del Greco shipyards. This section was completed in 2001 with the section transported to the Nemi museum where the rest of the vessel was to be constructed. The estimated final cost of the reconstruction was 7.2 million Euros (US$10.7 million). According to the Association Dianae Lacus website, on 15 November 2003 large Italian employer and business confederation Assimpresa announced its immediate sponsorship of all timber required for the construction. No press releases have been made since 2004. The Dianae Lacus web site was deleted on 1 October 2011.
