What is the second oldest monument in NYC?

The Worth Monument, which is indeed the correct answer, holds the distinction of being the second oldest monument in New York City. Erected in 1857 and dedicated to Major General William Jenkins Worth, it stands in Cadman Plaza Park in Brooklyn. The monument honors Worth's service in the Mexican-American War and is a notable piece of public art from the 19th century.

In contrast, the other options do not fit the criteria of being the second oldest monument. The Statue of Liberty, although iconic and older than the Worth Monument, was dedicated later in 1886. The Washington Monument in Washington, D.C., is also older than the Worth Monument but does not pertain to New York City's landscape. Finally, while the George Washington Bridge is a significant engineering landmark and was completed much later in 1931, it is not classified as a monument in the same sense as the Worth Monument. Thus, the Worth Monument is correctly recognized as the second oldest monument in New York City.
