The two ships were effectively floating palaces, equipped with plumbing, heating, and intricate marble floors.
The vessels were recovered by pumping water out of Lake Nemi into an existing ancient drainage tunnel, effectively lowering the lake level.
The wooden hulls were destroyed during a fire in May 1944; only metal fittings, anchors, and a few wooden fragments survived.
The museum building was designed by architect Vittorio Ballio Morpurgo in the 1930s to function as a hangar for the ships.
The ships were likely used for religious ceremonies associated with the cult of Diana, the goddess of the hunt, worshipped at the adjacent sanctuary.
The anchors used on the ships were remarkably advanced for the time, featuring adjustable arms, a design that was not widely adopted until the modern era.
Lake Nemi is a volcanic crater lake, and its unique environmental conditions contributed to the preservation of the wooden ships for nearly two millennia.
The Museo delle Navi Romane is a purpose-built architectural space specifically designed to house the remains of two massive, ceremonial imperial ships commissioned by Emperor Caligula. The original vessels were recovered from the depths of Lake Nemi during a major drainage project between 1928 and 1932. The museum structure follows the design of a hangar, reflecting the dimensions required to protect the original ship hulls. Following the destruction of the originals by fire in 1944, the museum now displays highly accurate 1:5 scale models alongside the surviving metal and structural artifacts. The site sits on the northern shore of the volcanic Lake Nemi in the Alban Hills. Archaeological finds from the surrounding sanctuary of Diana Nemorensis are also exhibited within the collection. The museum serves as a specialized research center for maritime archaeology and Roman naval engineering.

Combine your visit with a walk along the perimeter of Lake Nemi for views of the crater rim.
Check the official website for rotating temporary exhibitions regarding underwater archaeology in the Lazio region.
Bring light layers, as the large, high-ceilinged hangar can be cooler than the outdoor temperatures.
Do not attempt to walk down the steep banks directly to the lake from the museum; use designated public trails.
Typically closed on Mondays.
Maintain a quiet volume; photography is permitted for personal use but avoid using flash near sensitive artifacts.
