Ellis Island in the context of "Locust Point, Baltimore"

Castle Clinton (also known as Fort Clinton and Castle Garden) is a restored circular sandstone fort within Battery Park at the southern end of Manhattan in New York City, United States. Built from 1808 to 1811, it was the first American immigration station, predating Ellis Island. More than 7.5 million people arrived in the United States at Fort Clinton between 1855 and 1890. Over its active life, it has also functioned as a beer garden, exhibition hall, theater, and public aquarium. The structure is a New York City designated landmark and a U.S. national monument, and it is listed on the National Register of Historic Places.

Fort Clinton was originally known as the West Battery or the Southwest Battery, occupying an artificial island off the shore of Lower Manhattan. Designed by John McComb Jr., with Jonathan Williams as consulting engineer, the fort was garrisoned in 1812 but was never used for warfare. In 1824, the New York City government converted Fort Clinton into a 6,000-seat entertainment venue known as Castle Garden, which operated until 1855. Castle Garden then served as an immigrant processing depot for 35 years. When the processing facilities were moved to Ellis Island in 1892, Castle Garden was converted into the first home of the New York Aquarium, which opened in 1896 and continued operating until 1941. The fort was expanded and renovated several times during this period.

The New York–New Jersey Harbor Estuary, also known as the Hudson-Raritan Estuary, is in the northeastern states of New Jersey and New York on the East Coast of the United States. The system of waterways of the Port of New York and New Jersey forms one of the most intricate natural harbors in the world and one of the busiest ports of the United States. The harbor opens onto the New York Bight in the Atlantic Ocean to the southeast and Long Island Sound to the northeast.

Although the overall form of the estuary remains unchanged from the time of Giovanni da Verrazzano's visit in 1524, all parts have changed at least a little, and some parts, such as Hell Gate and Ellis Island, have been almost completely altered. In the greatest hidden change, the navigational channels have been deepened from the natural 17 feet (5.2 m) depth to 45 feet (14 m). In some places this required blasting of bedrock.

The Battery, formerly known as Battery Park, is a 25-acre (10 ha) public park located at the southern tip of Manhattan Island in New York City facing New York Harbor. The park is bounded by Battery Place on the north, with Bowling Green to the northeast, State Street on the east, New York Harbor to the south, and the Hudson River to the west. The park contains attractions such as an early 19th-century fort named Castle Clinton; multiple monuments; and the SeaGlass Carousel. The surrounding area, known as South Ferry, contains multiple ferry terminals, including the Staten Island Ferry's Whitehall Terminal; a boat launch to the Statue of Liberty National Monument (which includes Ellis Island and Liberty Island); and a boat launch to Governors Island.

The park and surrounding area are named for the artillery batteries that were built in the late 17th century to protect the fort and settlement behind them. By the 1820s, the Battery had become an entertainment destination and promenade, with the conversion of Castle Clinton into a theater venue. During the mid-19th century, the modern-day Battery Park was laid out and Castle Clinton was converted into an immigration and customs center. The Battery was commonly known as the landing point for immigrants arriving in New York City until 1892, when the immigration center was relocated to Ellis Island in the middle of the harbor. Castle Clinton (sometimes called, Castle Garden) then hosted the New York Aquarium from 1896 to 1941.

New York City received a ninth consecutive annual record of approximately 65.2 million tourists in 2018, the busiest tourist city attraction, and one of the world's overall busiest tourist attractions, counting not just overnight visitors but anyone visiting for the day from over 50 miles away, including commuters. Overall the city welcomed 37.9 million visitors who stayed overnight in 2018, of whom 13.6 million were international. Major destinations include the Empire State Building, Ellis Island, the Statue of Liberty on Liberty Island, Broadway theatre productions, Central Park, Times Square, Coney Island, the Financial District, museums, and sports stadiums. Other major visitor activities include luxury shopping along Fifth and Madison Avenues; entertainment events such as the Tribeca Film Festival; Randalls Island music festivals such as Governors Ball, Panorama and Electric Zoo; and free performances in Central Park at Summerstage and Delacorte Theater. Many New York City ethnic enclaves, such as Jackson Heights, Flushing, and Brighton Beach are major shopping destinations for first and second generation Americans.

New York City has over 28,000 acres (110 km) of parkland and 14 linear miles (22 km) of public beaches. Manhattan's Central Park, designed by Frederick Law Olmsted and Calvert Vaux, is the most visited city park in the United States. Prospect Park in Brooklyn, also designed by Olmsted and Vaux, has a 90-acre (36 ha) meadow. Flushing Meadows–Corona Park in Queens, the city's fourth-largest, was the setting for the 1939 World's Fair and 1964 World's Fair.

The Gateway Region is the primary urbanized area of the northeastern section of the U.S. state of New Jersey. The region is anchored by Newark, the state's most populous city, and constitutes part of the New York metropolitan area.

The area encompasses Bergen, Essex, Hudson, Passaic, Union, and Middlesex counties. It is the most urban part of the state, with a population of more than four million, and is home to most of its larger cities, though much housing was originally developed as suburbs of neighboring New York City. It is home to Ellis Island, the "gateway" through which many immigrants entered the United States, many of whom chose to stay in the region, which continues to be the port of entry and first home to many born abroad, making it one of the most ethnically diverse of the nation. It may also be the most socio-economically diverse, with some of the biggest pockets of poverty and most exclusive of suburbs in the state.

The Statue of Liberty National Monument is a United States national monument comprising Liberty Island and Ellis Island in the states of New Jersey and New York. It includes the 1886 Statue of Liberty (Liberty Enlightening the World) by sculptor Frédéric Auguste Bartholdi and the Statue of Liberty Museum, both situated on Liberty Island, as well as the former immigration station at Ellis Island, which includes the Ellis Island Immigrant Hospital.

The monument is managed by the National Park Service as part of the National Parks of New York Harbor office.

South Ferry is at the southern tip of Manhattan in New York City and is the embarkation point for ferries to Staten Island (Staten Island Ferry, through the Staten Island Ferry Whitehall Terminal) and Governors Island. Battery Park, abutting South Ferry on the west, has docking areas for ferries to Liberty Island and Ellis Island. Its name is derived from the more southerly route of service of the historical South Ferry Company in comparison to the Fulton Ferry.
