Castle Clinton (Manhattan, New York)
Manhattan · New York · War of 1812
History & Significance
Castle Clinton National Monument was one of more than a dozen forts built to defend New York Harbor at the time of the War of 1812. Completed in 1811 with 28 thirty-two-pounder cannons, the roughly circular fort was built on an artificial island just offshore.
The fort was garrisoned in 1812 but was never used for warfare. In 1817 the fort was renamed Castle Clinton in honor of DeWitt Clinton, Mayor and later Governor of New York.
The army vacated the fort in 1821 and the structure was deeded to New York City in 1823. It became the first American immigration station, predating Ellis Island, and on August 3, 1855, Castle Garden opened as an immigrant landing depot; during the next 34 years, over 8 million people entered the United States through Castle Garden, until it closed on April 18, 1890.
The building reopened as the New York City Aquarium on December 10, 1896. After preservation efforts in 1946 created the Castle Clinton National Monument, the National Park Service took over the fort in 1950. Castle Clinton reopened in 1975 following an extensive renovation.
