Fort Ontario Emergency Refugee Shelter

The Safe Haven Museum and Education Center is a museum in Oswego, New York that tells the story of 982 mainly Jewish refugees who fled Europe in the U.S. Government "Safe Haven" program. They came to the Fort Ontario Emergency Refugee Shelter in Oswego, New York, in August 1944. Safe Haven was the only official U.S. Government activity to rescue Jewish refugees during the Second World War, for victims of the Nazi Holocaust. The refugees were brought from Italy, but deliberately only from other parts of Europe. They were all fleeing from the Nazis. They were deliberately chosen so that some incoming refugees were non-Jewish, so as to allay anti-semitic fears. They were placed in Fort Ontario, behind barbed wire, and given no official status, and were told they would be returned to their homelands after the war, and would have no rights as regards entering the United States. In fact, due to political pressure, at the war's end they were allowed to stay in the United States. Parenthetically, the group included a whole group of Boy Scouts.

The Port of Oswego is the main waterfront area of the City of Oswego in Oswego County, New York. Over the course of its history, the Port of Oswego has been the focus of military conflict and conquest, asite of record trade revenue, and a significant part in the History of American expansion and industrialism. Today the Port of Oswego is a shadow of its once-powerful self but still proves to be useful as trade continues in the central New York region. Early explorers in the 17th century of Dutch, French, and English origin realized the value of an all-water route connecting the French settlements along the St. Lawrence River with the Dutch settlement of New Amsterdam. This would create a trade route that would stretch well over 500 miles (800 km) and give the controller of this route a significant advantage for turning profits in the New World. The Port of Oswego would become the focal point of this perceived route and bring the country that owns it almost infinite resources for constructing an empire in the New World. The history of activity at the Port can be divided into four great periods of development: The Fur Trading Era, The Salt Era, The Lumber and Grain Era, and The Coal Era.
