The Metropolitan Museum of Art opens in New York City.

The Metropolitan Museum of Art of New York City, colloquially "the Met", is the largest art museum in the Western Hemisphere. Its permanent collection contains over two million works, divided among 17 curatorial departments. The main building at 1000 Fifth Avenue, along the Museum Mile on the eastern edge of Central Park on Manhattan's Upper East Side, is by area one of the world's largest art museums. A much smaller second location, The Cloisters at Fort Tryon Park in Upper Manhattan, contains an extensive collection of art, architecture, and artifacts from medieval Europe.

The Metropolitan Museum of Art was founded in 1870 to bring art and art education to the American people. The museum's permanent collection consists of works of art from classical antiquity and ancient Egypt, paintings, and sculptures from nearly all the European masters, and an extensive collection of American and modern art. The Met maintains extensive holdings of African, Asian, Oceanian, Byzantine, and Islamic art. The museum is home to encyclopedic collections of musical instruments, costumes, and accessories, as well as antique weapons and armor from around the world. Several notable interiors, ranging from 1st-century Rome through modern American design, are installed in its galleries.

The Fifth Avenue building opened on February 20, 1872, at 681 Fifth Avenue. In 2020, it was closed for 202 days due to the COVID-19 pandemic, and attracted only 1,124,759 visitors. This was a drop of 83 percent from 2019, but the Met still ranked ninth on the list of most-visited art museums in the world.
