The Lusitania Propeller in Dallas is a haunting relic from the ill-fated RMS Lusitania, the luxury liner torpedoed by a German U-boat in 1915. This massive propeller, displayed with solemn dignity, is more than just an engineering marvel—it's a tangible piece of World War I history. At the Dallas Maritime Museum, you can examine its impressive scale and craftsmanship up close, while immersive exhibits transport you back to the ship's tragic final voyage. Don't miss the chance to touch its weathered bronze surface, where the chill of the deep sea still lingers.
