Fodor's Expert Review Museum für Antike Schifffahrt
The main attractions at this bright, airy museum are the fascinating remains of five 4th-century wooden Roman warships, on display with two full-size replicas. The remains were unearthed in 1981, when the foundation for an expansion to the Hilton hotel was dug. For more than a decade, the wood was injected with a water-and-paraffin mixture to restore its stability. There's also an extensive exhibit dedicated to the history of shipbuilding and an educational area for children. To arrange a tour, contact the service office.
