If it makes any sense, Lady Liberty was gifted to the US as a token of appreciation for their help in the war. It is made of copper and iron but since then it has taken on a greenish color due to the oxidization of the copper.
Yes one ferry make all the trip
I do not understand that question. But Lady Liberty is located on Liberty Island across New York, and New Jersey. There is also an Island nearby called Ellis which contains a museum for those who immigrated to form the United States. You take a ferry to reach that Island as well.
