The main court is located at the 24,000-seat Arthur Ashe Stadium, named after Arthur Ashe, the African American tennis player who won the inaugural men's final of the US Open in 1968.
The second court (Court Number 2) is Louis Armstrong Stadium, which stood as the main stadium until the completion of Ashe stadium.
The DecoTurf surface at the US Open is a fast surface, having slightly less friction and producing a lower bounce compared to other hard courts.
The event was first held in August 1881 and staged at the Newport Casino, Newport, Rhode Island (men's singles only).
Six years after the men's nationals were held, the first official US Women's National Singles Championship was held at the Philadelphia Cricket Club in 1887, followed by the US Women's National Doubles Championship in 1889.
The first US Mixed Doubles Championship was held alongside the women's singles and doubles.
