[PAR] [TLE] Ellis Island [SEP] Ellis Island, in Upper New York Bay, was the gateway for over 12 million immigrants to the United States as the nation's busiest immigrant inspection station for over sixty years from 1892 until 1954.  The island was greatly expanded with land reclamation between 1892 and 1934.  Before that, the much smaller original island was the site of Fort Gibson and later a naval magazine.  The island was made part of the Statue of Liberty National Monument in 1965, and has hosted a museum of immigration since 1990. [PAR] [TLE] Castle Clinton [SEP] Castle Clinton or Fort Clinton, previously known as Castle Garden, is a circular sandstone fort now located in Battery Park, in Manhattan, New York City.  It is perhaps best remembered as America's first immigration station (predating Ellis Island), where more than 8 million people arrived in the U.S. from 1855 to 1890.  Over its active life, it has also functioned as a beer garden, exhibition hall, theater, and public aquarium, and currently is a national monument.
