Los Angeles Maritime Museum, California

Located right next to the Port of Los Angeles, this museum houses what is probably the largest collection of model ships in the world. Among the 700 detailed specimens is a 18-foot Titanic, a Department of Energy research vessel, numerous military vessels, and, though no such ship existed, there is an elaborate 22-foot model of the Poseidon, made for the 1972 movie "The Poseidon Adventure."
