The Nuestra Señora de la Concepción (German: "Our Lady of the [Immaculate] Conception") was a very large Spanish Manila galleon , which in 1638 - richly loaded with Far Eastern goods - was on the journey from Manila to Acapulco . On September 20, she ran into a fringing reef in Agingan Bay in southwest Saipan , the main island of the Northern Mariana Islands . Few of the 400 or so sailors and passengers on board survived the ship's sinking; six of them managed to reach Guam by boat , from where they returned to Manila and reported on the disaster. The Nuestra Señora de la Concepción was between 140 and 160 feet long (about 42 to 49 meters) and had a displacement of 2,000 tons. In the mid-1980s, the ship's wreck was rediscovered and finally salvaged in 1987.
