Citi Field is a stadium located in Flushing Meadows–Corona Park in the New York City borough of Queens. Completed in 2009, it is the home baseball park of Major League Baseball's New York Mets. Citi Field was built as a replacement for the formerly adjacent Shea Stadium, which opened in 1964 next to the site of the 1964–1965 World's Fair. Citi Field was designed by Populous (then HOK Sport), and is named after Citigroup, a New York financial services company which purchased the naming rights.
