Happy Birthday? Happy Anniversary? In this case it’s one and the same since today, February 20th is the day that the Metropolitan Museum of Art opened it’s doors in Manhattan in 1872. Originally, it resided in a rented space at 681 Fifth Avenue and moved several times before migrating to the east side of Central Park to the home we know today (at 1000 Fifth Avenue). The Metropolitan Museum of Art is now more than 2 million square feet and contains more than 2 million works of art divided into nineteen curatorial departments.
