Statue of Liberty and Ellis Island National Monuments
A welcome sight to new immigrants, the Statue of Liberty Enlightening the World was a gift of friendship from the people of France to the people of the United States. Opened on January 1, 1892, Ellis Island became the nation's premier federal immigration station. In operation until 1954, the station processed over 12 million immigrant steamship passengers.
The cry was FREE LAND! The Homestead Act of 1862 was one of the most significant and enduring events in the westward expansion of the United States. By granting free land, it allowed nearly any man or woman a chance to live the American dream.
On May 10, 1869 the Union and Central Pacific Railroads joined their rails at Promontory Summit and became this nation's first transcontinental railroad.
