Caligula has two large ships constructed for himself, which will be recovered from the bottom of Lake Nemi during the dictatorship of Benito Mussolini.
The ships are among the largest vessels in the ancient world.
The smaller ship is designed as a temple dedicated to Diana.
The larger ship is essentially an elaborate floating palace that counts marble floors and plumbing among its amenities.
Thirteen years after being raised, the ships were burned during an attack in the Second World War, and almost nothing remains of the hulls, though many archaeological treasures remain intact in the museum at Lake Nemi and in the Museo Nazionale Romano (Palazzo Massimo) at Rome.
